  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);    //现在three=30

          System.out.println(three+=one);    //现在three=40

          System.out.println(three-=one);    //现在three=30 

          System.out.println(three*=one);    //现在three=300

          System.out.println(three/=one);    //现在three=30

          System.out.println(three%=one);    //现在three=0

  /*

  每一次输出都在对three重新赋值然后进行下面的继续运算

  不知道这样说合理不

   three+=one;

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

  //这时候等于40

           three-=one;

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

  //这时候用上个式子的结果再减one就是40-10也就等于30了

  //第一行是说three= one + two ==> +three 所以是等于30

  //第二行是说three += one ==> +three  所以是等于40

  //第三行是说three -= one ==> +three 所以是用40-10+0=30
