Thread: Beginners Eclipse Tutorial. How to run first java application on Eclipse?

Beginners Eclipse Tutorial

In this tutorial I will show you how to use the Eclipse IDE for the first time.

Firstly, download the latest version of Eclipse.

Eclipse Downloads

Here is a direct link to the download:

Eclipse downloads - mirror selection

Once its downloaded & installed, double click the Eclipse icon to start.



Because this is your first time running Eclipse, it will take a while to load as it sets up the environment.



Once Eclipse is fully loaded you will see the Welcome Screen. You can close this straight away..



OK now lets start our first application.

Click File > New > Java Project



The 'Create a Java Project' box will popup.

Give your Project a name. In this case I have named it 'EclipseTutorial'



Click FINISH.

You have now setup your first project which will appear in the Package Explorer window.



Before we can begin to write any code, we must first add a Package which will contain all our project files.

Make sure your new project is highlighted and click the 'New Java Package' icon.



Give your package a name relevant to your project.



Click FINISH

Now your Package has been created we need to add a Class file. Make sure the Package is highlighted by clicking it once and then click the 'New Java Class' icon.



The Create a New Java Class box will popup.

Give your Class a name and tick the public static void main(String[] args) box.



Your Class will now appear in the Workspace and you are ready to start writing code!



Here I have wrote a simple Hello World application which will print the words into the console.



To Run your Java project. Right click the 'TutorialClass.java' file in the Package Explorer window, then click Run As > Java Application



The output will now be displayed in the console.



Congratulations! You have just wrote your first Java application in Eclipse!!

To date, I've always used NetBeans IDE and I'm just wondering, would you recommend Eclipse over NetBeans baring In mind I use Glass-fish container with it (not sure if Glass-fish is supported by Eclipse)?. Or would there be any significant advantages to switching from NetBeans to Eclipse?
Thanks.

Hello newbie,

It all depends the type of programming you do I guess. I first started in Eclipse because the applications I needed to write were command line based. There was no need for a GUI.
As you know, NetBeans is great for creating GUIs. If I required GUIs, I probably would have started with NetBeans.

I personally haven't used Glass-Fish so I'm not sure if it is supported within Eclipse or not. Eclipse is a very powerful IDE though with many plugins so chances are it is supported.

It all boils down to what you are comfortable with. Always worth giving Eclipse a try

Here is a shortcut for beginners to use.

write : main then CTRL+SPACE ----> gives u the full Main statement
write: sysout then CTRL+SPACE -----> gives you System.out.println(); statement.

if you need to know the function of a particular object then do. yourObject.(CTRL+SPACE)
