Question

public class Hassan {
int a = 0;
double b = 0.0;
String s = "Hello world";
public Hassan(int a){
this.s = "this is int";
}
public Hassan(double b){
this.s = "this is double";
}
public void shows(){
System.out.println(s);
}

public static void main(String[] args) {
    // TODO 自动生成的方法存根
Hassan h1 = new Hassan(100);
h1.shows();
Hassan h2 = new Hassan(100.0);
h2.shows();

你这个程序本身没有问题，是Debug导致出现的问题 ，解决方法网上很多：

文章中提到的链接也看一下（在main函数结束时，添加system.exit(0)；）
