int QQ=three=one+two;            //20+10=30

int EE=three-=one;                  //40-10=30     注释部分是自己口算结果

int RR=three*=one;                 //30*10=300

int TT=three/=one;                 //300/10=30

int YY=three%=one;                 //30%10=0

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

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

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

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

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

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

}

}

  输出结果如下；

three=one+two==>30

three+=one==>40

three-=one==>20

three*=one=>200

three/=one==>20

three%=one=>0
