  我的代码：

  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*=one;

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

          three/=one;

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

          three%=one;

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

      }

  }
