After installation, all of them are installed by the default option.

Then start creating the first project, HelloWorld

Once created, right-click the SRC folder, add the package, and add the HelloWorld class to the package

Then put the code in the file:

 Package HelloWorld; Import Java.lang.System;  Public class HelloWorld {    publicstaticvoid  main (string[] args) {        System.out.println ("Hello world!" );    }}

Tap Run, run the program, select HelloWorld, and the code runs.
