JAVA equals（）方法重写

public static void main(String[] args) {
// TODO Auto-generated method stub
        one s=new one();
        one ss=new one();
        if(s.equals(ss)){
        System.out.println("hao");
        }else{
        System.out.println("no");
        } 
}


@Override
public boolean equals(Object obj) {
if (this == obj)
return true;
if (obj == null)
return false;
if (getClass() != obj.getClass())
return false;
one other = (one) obj;
if (a != other.a)
return true;//类对象与类的对象的区别
return true;
}


}
