  public class HelloWorld{

      public static void main(String[] args) {

     int one = 10 ;

          int two = 20 ;

          int three = 0 ;

          three=one+two;     

       System.out.println("three = one + two ==> "+three);

          three+=one;

          System.out.println("three += one ==> "+three);

          three-=one;

          System.out.println("three -= one ==> "+three);

          three*=one;

          System.out.println("three *= one ==> "+three);
