SYS-CON Webcast: Eclipse IDE for Students, Useful Eclipse Tips & Tricks

Lesson 10 In The Hugely Popular "Java Basics" SYS-CON.TV Education Series by Yakov Fain

In Lesson 10 of the Java Basics series Yakov Fain shows you how to start working with Eclipse IDE, which is a tool of choice for millions of professional Java programmers. After reading this article you may want to look at another of Yakov's articles for youngsters "Teaching Kids Programming: Even Younger Kids can Learn Java".

Moving to Eclipse

Programmers usually work in a so-called Integrated Development Environment (IDE). You can write, compile and run programs there. An IDE also has a Help thingy that describes all elements of the language, and makes it easier to find and fix errors in your programs. While some IDE programs are expensive, there is an excellent free IDE called Eclipse. You can download it from the Web site www.eclipse.org. In this chapter I'll help you to download and install Eclipse IDE on your computer, create a project there called Hello World, and after this we'll be creating all our programs there.

Make yourself comfortable in Eclipse - it's an excellent tool that many professional Java programmers use.

Installing Eclipse

Open the Web page www.eclipse.org and click on the Download menu on the left (http). Click on the link Main Eclipse Download Site and select the version of Eclipse you want to download. They usually have one latest release and several stable builds. The latest release is an officially released product. Even though stable builds may have more features, they still may have some minor problems. At the time of this writing the latest stable build is 3.0M8.

Select this build and you'll see the following window:

 

Click on the link (http) next to the word Windows, Mac, or Linux depending on your computer, and download the file with this long name that ends with .zip to any folder on your disk.

 

 

Installation of Eclipse is complete! For your convenience, create the shortcut for Eclipse on your desktop. Right-click on the Windows desktop, then press New, Shortcut, Browse, and select the file eclipse.exe in the folder c:\eclipse. To start the program, double-click on the blue icon Eclipse, and you'll see the first Welcome screen (this screen is changing slightly with each Eclipse build):

 

If your screen looks different, proceed to so-called Workbench, which is the working area for your Java projects.

Getting Started with Eclipse

In this section I'll show you how you can quickly create and run Java programs in Eclipse. You can also find a nice tutorial under the menus Help, Help Contents, and Java Development User Guide.

To start working on a program you'll need to create a new project. A simple project like our HelloWorld will have just one file - HelloWorld.java. Pretty soon we'll create more advanced projects that will consist of several files.

To create a brand new project in Eclipse just click on the menus File, New, Project, and then press the button Next on the New Project window. Now you'll need to enter the name of your new project, for example My First Project:

 

Look at the grayed out box Directory. It tells you where the files of this project will be located on the disk. Eclipse has a special folder workspace, where it keeps all files for your projects. Later on, you can create separate projects for a calculator program, a Tic-Tac-Toe game, and other programs.

Eclipse workbench has several smaller areas called perspectives which are different views of your projects.

 

If you click on the little plus sign by My First Project, it'll expand showing you an item Java Run-time Environment (JRE) System Library which is a part of the project. If for any reason you do not see JRE there, click on the menus Windows, Preferences, Java, Editor, Installed JREs, Add, and, using the button Browse find the folder where you have installed Java, for example c:\j2sdk1.5.0.

Creating Programs in Eclipse

Let's recreate the HelloWorld program from Chapter 1 of my e-book Java Programming for Kids, Parents and Grandparents in Eclipse. Java programs are classes that represent objects from real life. You'll learn more about classes in the next chapter.

To create a class in Eclipse select the menus File, New, Class and enter HelloWorld in the field Name. Also, in the section Which methods stubs you would like to create, check off the box

public static void main(String[] args)

 

Press the button Finish, and you'll see that Eclipse created for you the class HelloWorld. It placed program comments (the text between /* and */) on top - you should change them to describe your class. After the comments you'll find the code of the class HelloWorld with an empty method main(). The word method means action. To run a Java class as a program, this class must have a method called main().

 

To complete our program, place the cursor after the curly brace in the line with main, push the button Enter and type the following on the new line:

System.out.println("Hello World");

To save the program on disk and compile it, just press at the same time two buttons on your keyboard: Ctrl-S. If you did not make any syntax errors, you won't see any messages - the program is compiled. But let's make an error on purpose to see what's going to happen. Erase the last curly brace and hit Ctrl-S again. Eclipse will display the Unmatched Brace error in the tasks perspective, and also it will place a red mark by the line that has a problem.

As your projects become larger, they'll have several files and compiler may generate more than one error. You can quickly find (not fix though) the problematic lines by double-clicking on the error message in the tasks perspective. Let's put the curly brace back and hit Ctrl-S again - voila, the error message is gone!

Running HelloWorld in Eclipse

Our simple program is a one-class project. But pretty soon your projects will have several Java classes. That's why before running the project for the first time, you need to tell Eclipse which class in this project is the main one.

Select the menu Run, then Run...(make sure that Java Application is selected in the top left corner), and enter the names of the project and the main class:

 

Now press the button Run, to start the program. It will print the words Hello World in the console view the same way as it did in Chapter 1.

You can run this project by selecting the menus Run, Run Last Launched or by pressing the buttons Ctrl-F11 on the keyboard.

How HelloWorld Works?

Let's start learning what's actually happening in the program HelloWorld.

The class HelloWorld has only one method main(), which is an entry point of a Java application (program). You can tell that main is a method, because it has parentheses after the word main. Methods can call (use) other methods, for example our method main() calls the method println() to display the text Hello World on the screen.

Each method starts with a declaration line called a method signature:

public static void main(String[] args)

This method signature tells us the following:

  • Who can access the method - public. The keyword public means that the method main() could be accessed by any other Java class or JVM itself.
  • Instructions on how to use it - static. The keyword static means that you don't have to create an instance (a copy ) of HelloWorld object in memory to use this method. We'll talk about instances more in the next chapter.
  • Does the method return any data? The keyword void means that the method main() doesn't return any data to the calling program, which is Eclipse in this case. But if for example, a method had to perform some calculations, it could have returned a resulting number to its caller.
  • The name of the method is main.
  • The list of arguments - some data that could be given to the method - String[] args. In the method main() the String[] args means that this method can receive an array of Strings that represent text data. The values that are being passed to a method are called arguments.

As I said before, you can have a program that consists of several classes, but one of them has the method main(). Java class usually have several methods. For example, a class Game can have the methods startGame(), stopGame(), readScore(), and so on.

The body of our method main()has only one line :

System.out.println("Hello World");

Every command or a method call must end with a semicolon ;. The method println()knows how to print data on the system console (command window). Method names in Java are always followed by parentheses. If you see a method with empty parentheses, this means that this method does not have any arguments.

The System.out means that the variable out is defined inside the class System that comes with Java. How are you supposed to know that there's something called out in the class System? Eclipse will help you with this. After you type the word System and a dot, Eclipse will show you everything that is available in this class. At any time you can also put a cursor after the dot and press Ctrl-Space to bring up a help box similar to this one:

 

The out.println() tells us that there is an object represented by a variable out and this "something called out" has a method called println(). The dot between a class and a method name means that this method exists inside this class. Say you have a class PingPongGame that has a method saveScore(). This is how you can call this method for Dave who won three games:

PingPongGame.saveScore("Dave", 3);

Again, the data between parentheses are called arguments or parameters. These parameters are given to a method for some kind of processing, for example saving data on the disk. The method saveScore() has two arguments -a text string "Dave", and the number 3.

Eclipse will add fun to writing Java programs. The Appendix below has some useful tips and tricks that will speed up your Java programming in this excellent IDE.

Appendix: Eclipse Tips

Eclipse has many little convenient commands that make Java programming a little easier. I've included some useful Eclipse tips here, but I'm sure you'll find more when you start using this tool.

  • If you see a little asterisk in the tab with the class, this means that the class has unsaved code changes.
  • Highlight the name of the class or a method that is used in your code and press the button F3 on your keyboard. This will take you to the line where this class or method was declared.
  • If some of the lines are marked with red error circles, move the mouse over the circle to see the error text.
  • Press Ctrl-F11 to run the last-launched program again.
  • Place the cursor after a curly brace and Eclipse will mark the matching brace.
  • To change the superclass when creating a new class, click on the button Browse, delete the class java.lang.Object and enter the first letter of the class you'd like to use. You'll see a list of available classes to choose from.
  • To copy a class from one package to another, select the class and press Ctrl-C. Select the destination package and press Ctrl-V.
  • To rename a class, a variable or a method, right-click on it and select Refactor and Rename from the popup menu. This will rename every occurrence of this name.
  • If your project needs some external jars, right-click on the project name, select Properties, Java Build Path and press the button Add External Jars.

Eclipse Debugger

Rumor has it that about 40 years ago, when computers were large and would not even fit in your room, all of a sudden one of the programs started giving wrong results. All these troubles were caused by a small bug that was sitting inside the computer somewhere in the wires. When people removed the bug, the program started working properly again. Since then, to debug a program means to find out why it does not give the expected results.

Do not confuse bugs with the compilation errors. Say for example, instead of multiplying the variable by 2, you'll multiply it by 22. This typo will not generate any compilation errors, but the result will be incorrect. Debuggers allow you to step through a running program one line at a time, and you can see and change values of all variables at each point of the program execution.

 

I'll show you how to use Eclipse debugger using the FishMaster program from Chapter 4 of my e-book  Java Programming for Kids, Parents and Grandparents.

A breakpoint is a line in the code where you'd like program to pause so you can see/change current values of the variables, and some other run-time information. To set a breakpoint just double click on the gray area to the left of the line where you want a program to stop. Let's do it in the FishMaster class on the line myFish.dive(2). You'll see a round bullet on this line which is a breakpoint. Now, select the menus Run, Debug.... Select the application FishMaster and press the button Debug.

FishMaster will start running in the debug mode, and as soon as the program reaches the line myFish.dive(2), it will stop and will wait for your further instructions.

You will see a window similar to the next one.

 

In the left bottom part of the debug perspective, you see that the line with the breakpoint is highlighted. The blue arrow points at the line that is about to be executed. On the right side (in the Variables view) click on the little plus sign by the variable myFish. Since this variable points at the object Fish, you will see all member variables of this class and their current values, for example currentDepth=20.

The arrows in the top left area allow you to continue execution of the program in different modes. The first bended yellow arrow means step into the method. If you press this arrow (or F5), you'll find yourself inside the method dive(). The window changes and you see the values of the argument howDeep=2 as in the next screenshot. Click on the little plus by the word this to see what are the current values of member variables of this object.

To change the value of the variable, right-click on the variable and enter the new value. This can help when you are not sure why the program does not work correctly and would like to play what if game.

 

To continue execution one line at a time, keep pressing the next arrow step over (or the button F6).

If you want to continue program in the fast mode, press a small green triangle or the button F8.

To remove the breakpoint just double-click on the little round bullet and it'll disappear. I like using debugger even if my program does not have a bug - it helps me better understand what exactly happens inside the running program.

Where to put a breakpoint? If you have an idea which method gives you problems, put it right before the suspicious line of code. If you are not sure, just put it in the first line of the method main() and slowly walk through the program.

FYI, NetBeans is also a free, open source Java IDE that is great for students learning Java. The current stable version is 4.0 and 4.1 is in beta. Downloads are available at:

http://www.netbeans.org/downloads/index.html.

Two great tutorials for getting started quickly are at:

http://www.netbeans.org/kb/articles/quickstart-40.html
http://www.netbeans.org/kb/articles/quickstart-webapps-40.html

Tony Austin 04/04/05 08:37:21 AM EDT

Yakov, thanks for the rapid reply!

No, I'm assuming that you already had a suitable JRE and JDK installed. (I already had been using NetBeans, JBuilder and other Java IDEs with these.)

It suddenly hit me what I've been doing wrongly. I have been unzipping the Eclipse platform downloads (such as eclipse-platform-3.0-win32.zip for Eclipse 3.0 or eclipse-platform-M20050311-win32.zip for Eclipse 3.1 M5). When you do this, you get an IDE that it doesn't have the JDT plug-in installed. If you're used most other IDEs (such as NetBeans, Visual Studio) typically install the compiler and other language development support are installed as part of the base installation procedure.

Some novices might not know of course Eclipse is a little different in this regard, being language-neutral. I did know about this, but still made the mistake of unzipping the wrong download.

When I unzipped the SDK download (such as eclipse-SDK-3.0-win32.zip for Eclipse 3.0 or eclipse-SDK-M20050311-win32.zip for Eclipse 3.1 M5) then sure enough the Java support was sitting there ready to be used "right out of the box" -- so everything is goodness if you do it this way.

If I made this simple mistake, then I'm prepared to bet that others will too. Therefore, let me modify my suggestion to recommend that users need to be warned to download and unzip the "SDK" version of Eclipse and not the "platform" version. Fair enough?

Yakov 04/04/05 06:39:44 AM EDT

Tony,

As I've mentioned in the article, installation of Eclipse is as simple as downloading and unzipping of the latest stable milestone or latest release.

Your problems may come from the fact that you do not realize that Eclipse does not come with its own Java Run Time.

To make it clear, if you have a brand new computer do the following:

1. Install Java from any of the vendors, i.e. http://java.sun.com/j2se/1.5.0/download.jsp (at the time of this writing you need to download Update 2).

2. Download and unzip latest stable milestone or latest release from eclipse.org.

Reagrds,
Yakov

Tony Austin 04/04/05 05:41:05 AM EDT

I am not in any way quibbling with the overall content of Yakov Fain's tutorial "Eclipse for Students & Eclipse Tips".

However -- unless I'm completely off track -- I'd say that there's one FATAL OMISSION in it.

I cannot find my downloads of Eclipse Version 2, but to the best of my knowledge for Eclipse V3, it is NOT correct for Yakov to state, immediately after the unzipping the Eclipse download, that the "Installation of Eclipse is complete!"

I cannot recall if it was different for Eclipse V2, but certainly for Eclipse V3 the novice has to learn that at this stage only the base Eclipse V3 has been installed.

As in several other introductory tutorials that I've examined, Yakov failed to explain that before you can work with Java code you have to (a) understand that the Java Development Toolkit (JDT) plug-in is not yet installed; then (b) Learn how to install plug-ins via the Eclipse Update Manager (EUM) via Help / Software Updates / Find and Install / Search for New Features to Install (and so on) -- not a trivial omission.

As one who tried using Eclipse V3 without reading any documentation, I spent quite a few hours completely frustrated, wondering where the Java support was! It wasn't until I stumbled across the plug-in installation process that I realized that the Java support (the JDT) was a plug-in and why Java was not included in the base download.

I DID look for a simple explanation of the process, but could NOT readily find any description of the procedure anywhere in the Eclipse online Help nor on the eclipse.org web site. Maybe it's there somewhere, but it's certainly hard to find! If anything, it should have been one of the FIRST things described in the Help and should be explained in a crystal-clear fashion somewhere on the web site. should it not?

I strongly recommend that the article be updated to incorporate with this critical procedure, otherwise I fear that the target audience (new to Eclipse, and maybe also to Java) will be quickly become as frustrated as I was at the start of my experimentation with Eclipse V3.

Tom Tran 03/25/05 08:21:34 AM EST

In comparing Eclipse and NetBeans, I found that creating a GUI application on NetBeans is easy. On Eclipse, I could not find a way to do it. Please any one point me to a good tutorial.

webmilhouse 03/23/05 04:59:01 AM EST

I don't know if you can fairly compare NetBeans and Eclipse, because Eclipse is more of an IDE platform where you can get scores of plugins related to different languages and tasks. There are plugins for C++, perl, python, PHP, XML, ColdFusion, UML, and a slew of others.

The java perspective in Eclipse is great, and runs much better on my SuSe laptop than NetBeans ever did. I ran NetBeans for a while but switched to Eclipse and never looked back. Plus, I only have to learn the eccentricities of one IDE for all my programming tasks, as opposed to many different ones.

gridlocker 03/23/05 04:56:03 AM EST

So, how is Eclipse compared to Sun's NetBeans?

Answer 03/23/05 04:52:58 AM EST

Most java shops I've seen use IntelliJ Idea. It's the best IDE if you have the cash. Eclipse has a large group of followers among the OSS crowd but, in my experience, SWT's performance leaves a lot to be desired on !Windows environments.

So how long before Eclipse kills all other (commercial) IDEs?

There will be 50 billion Internet connected devices by 2020. Today, every manufacturer has a propriety protocol and an app. How do we securely integrate these "things" into our lives and businesses in a way that we can easily control and manage? Even better, how do we integrate these "things" so that they control and manage each other so our lives become more convenient or our businesses become more profitable and/or safe? We have heard that the best interface is no interface. In his session at Internet of @ThingsExpo, Chris Matthieu, Co-Founder & CTO at Octoblu, Inc., will discuss how these devices generate enough data to learn our behaviors and simplify/improve our lives. What if we could connect everything to everything? I'm not only talking about connecting things to things but also systems, cloud services, and people. Add in a little machine learning and artificial intelligence and now we have something interesting...
Last week, while in San Francisco, I used the Uber app and service four times. All four experiences were great, although one of the drivers stopped for 30 seconds and then left as I was walking up to the car. He must have realized I was a blogger. None the less, the next car was just a minute away and I suffered no pain. In this article, my colleague, Ved Sen, Global Head, Advisory Services Social, Mobile and Sensors at Cognizant shares his experiences and insights.
We are reaching the end of the beginning with WebRTC and real systems using this technology have begun to appear. One challenge that faces every WebRTC deployment (in some form or another) is identity management. For example, if you have an existing service – possibly built on a variety of different PaaS/SaaS offerings – and you want to add real-time communications you are faced with a challenge relating to user management, authentication, authorization, and validation. Service providers will want to use their existing identities, but these will have credentials already that are (hopefully) irreversibly encoded. In his session at Internet of @ThingsExpo, Peter Dunkley, Technical Director at Acision, will look at how this identity problem can be solved and discuss ways to use existing web identities for real-time communication.
Can call centers hang up the phones for good? Intuitive Solutions did. WebRTC enabled this contact center provider to eliminate antiquated telephony and desktop phone infrastructure with a pure web-based solution, allowing them to expand beyond brick-and-mortar confines to a home-based agent model. It also ensured scalability and better service for customers, including MUY! Companies, one of the country's largest franchise restaurant companies with 232 Pizza Hut locations. This is one example of WebRTC adoption today, but the potential is limitless when powered by IoT. Attendees will learn real-world benefits of WebRTC and explore future possibilities, as WebRTC and IoT intersect to improve customer service.
From telemedicine to smart cars, digital homes and industrial monitoring, the explosive growth of IoT has created exciting new business opportunities for real time calls and messaging. In his session at Internet of @ThingsExpo, Ivelin Ivanov, CEO and Co-Founder of Telestax, will share some of the new revenue sources that IoT created for Restcomm – the open source telephony platform from Telestax. Ivelin Ivanov is a technology entrepreneur who founded Mobicents, an Open Source VoIP Platform, to help create, deploy, and manage applications integrating voice, video and data. He is the co-founder of TeleStax, an Open Source Cloud Communications company that helps the shift from legacy IN/SS7 telco networks to IP-based cloud comms. An early investor in multiple start-ups, he still finds time to code for his companies and contribute to open source projects.
The Internet of Things (IoT) promises to create new business models as significant as those that were inspired by the Internet and the smartphone 20 and 10 years ago. What business, social and practical implications will this phenomenon bring? That's the subject of "Monetizing the Internet of Things: Perspectives from the Front Lines," an e-book released today and available free of charge from Aria Systems, the leading innovator in recurring revenue management.
The Internet of Things will put IT to its ultimate test by creating infinite new opportunities to digitize products and services, generate and analyze new data to improve customer satisfaction, and discover new ways to gain a competitive advantage across nearly every industry. In order to help corporate business units to capitalize on the rapidly evolving IoT opportunities, IT must stand up to a new set of challenges.
There’s Big Data, then there’s really Big Data from the Internet of Things. IoT is evolving to include many data possibilities like new types of event, log and network data. The volumes are enormous, generating tens of billions of logs per day, which raise data challenges. Early IoT deployments are relying heavily on both the cloud and managed service providers to navigate these challenges. In her session at 6th Big Data Expo®, Hannah Smalltree, Director at Treasure Data, to discuss how IoT, Big Data and deployments are processing massive data volumes from wearables, utilities and other machines.
All major researchers estimate there will be tens of billions devices – computers, smartphones, tablets, and sensors – connected to the Internet by 2020. This number will continue to grow at a rapid pace for the next several decades. With major technology companies and startups seriously embracing IoT strategies, now is the perfect time to attend @ThingsExpo in Silicon Valley. Learn what is going on, contribute to the discussions, and ensure that your enterprise is as "IoT-Ready" as it can be!
P2P RTC will impact the landscape of communications, shifting from traditional telephony style communications models to OTT (Over-The-Top) cloud assisted & PaaS (Platform as a Service) communication services. The P2P shift will impact many areas of our lives, from mobile communication, human interactive web services, RTC and telephony infrastructure, user federation, security and privacy implications, business costs, and scalability. In his session at Internet of @ThingsExpo, Erik Lagerway, Co-founder of Hookflash, will walk through the shifting landscape of traditional telephone and voice services to the modern P2P RTC era of OTT cloud assisted services.
While great strides have been made relative to the video aspects of remote collaboration, audio technology has basically stagnated. Typically all audio is mixed to a single monaural stream and emanates from a single point, such as a speakerphone or a speaker associated with a video monitor. This leads to confusion and lack of understanding among participants especially regarding who is actually speaking. Spatial teleconferencing introduces the concept of acoustic spatial separation between conference participants in three dimensional space. This has been shown to significantly improve comprehension and conference efficiency.
The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, will discuss single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example to explain some of these concepts including when to use different storage models.

The Transparent Cloud-computing Consortium (abbreviation: T-Cloud Consortium) will conduct research activities into changes in the computing model as a result of collaboration between "device" and "cloud" and the creation of new value and markets through organic data processing High speed and high quality networks, and dramatic improvements in computer processing capabilities, have greatly changed the nature of applications and made the storing and processing of data on the network commonplace. These technological reforms have not only changed computers and smartphones, but are also changing the data processing model for all information devices. In particular, in the area known as M2M (Machine-To-Machine), there are great expectations that information with a new type of value can be produced using a variety of devices and sensors saving/sharing data via the network and through large-scale cloud-type data processing. This consortium believes that attaching a huge number of devic...

With the iCloud scandal seemingly in its past, Apple announced new iPhones, updates to iPad and MacBook as well as news on OSX Yosemite. Although consumers will have to wait to get their hands on some of that new stuff, what they can get is the latest release of iOS 8 that Apple made available for most in-market iPhones and iPads. Originally announced at WWDC (Apple’s annual developers conference) in June, iOS 8 seems to spearhead Apple’s newfound focus upon greater integration of their products into everyday tasks, cross-platform mobility and self-monitoring. Before you update your device, here is a look at some of the new features and things you may want to consider from a mobile security perspective.
