  public class HelloWorld{
      public static void main(String[] args) {
       int one = 10 ;
          int two = 20 ;
          int three = 0 ;
          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));
   }
  }

  不用增加变量，直接输出。

  要放在一起算  因为他每一次都运用了前一次的计算结果累计使用的，一次次的算每一次的数值都是初始的赋值  算起来当然不正确。

   int one = 10 ;        int two = 20 ;        int three = 0 ;         three=one+two;        int a=three+=one;        int b=three-=one;        int c=three*=one;        int d=three/=one;        int e=three%=one;         //你的所有System.out.println都错写为System.out.printlin了        System.out.println("three=one+two ==>"+three);    //题目里  ==>  是要打印的内容        System.out.println("three+=one ==>"+a);        System.out.println("three-=one ==>"+b);        System.out.println("three*=one ==>"+c);        System.out.println("three/=one ==>"+d);        System.out.println("three%=one ==>"+e);        }}
