 int one = 10;

        int two = 20;

        int three;

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

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

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

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

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

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