public class HelloWorld{

    public static void main(String[] args) {

   int one = 10 ;

        int two = 20 ;

        int three = 0 ;

        int three=one+two==>30;

        int three+=one==>40;

        int three-=one==>30;

        int three*+one==>300;

        int three/=one==>30;

        int three%/==>0

应用运算符实现：

        int three=one+two==>30;

        int three+=one==>40;

        int three-=one==>30;

        int three*+one==>300;

        int three/=one==>30;

        int three%/==>0

我很奇怪，总感觉不对。但是已经同过了测试题到底是什么回事？
