How can start programming with Java?

Favorite Answer

Well, for a start, you will need 3 things:

1) Java virtual machine (which you most likley already have)

2) Java software development kit (Java SDK), here is the latest version: https://cds.sun.com/is-bin/INTERSHOP.enfinity/WFS/CDS-CDS_Developer-Site/en_US/-/USD/ViewProductDetail-Start?ProductRef=jdk-6u14-oth-JPR@CDS-CDS_Developer

3) An IDE, I recommand Eclipse, simply download (its in a zip file) and run the eclipse.exe, no need to install anything




Once you install everything, run eclipse and lets make a hello world program:

1) File -> New -> Application Client Project

2) Project Name: Hello World

3) Finish

4) In the project explorer find Hello world and go to the
"appclientModule" folder, which is where your source files will be located

5) Go to the default package and open Main.Java

6) Put the following code in there:

public class Main {
     public static void main(String[] args) {
          System.out.println("Hello World!");
     }
}

7) Hit the play button (or Ctrl+F11)

If everything whant as it should the console window should have printed:

Hello World!

Congratulations! You are all set to explorer the wonderful world of Java!
