        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);

        three/=one;

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

        three%=one;
