public static void main(String[] args) { //主方法
Student s = new Student("张三",23);

boolean b = s.equals(s1); // s.equals(s1);相當于s調用equals（）方法，s1賦值equals
System.out.println(b);

}
}
public class Student {
@Override
public boolean equals(Object obj) {
//father f = new son(); object obj =s1=new Student("张三",23); 相当于是多态，父类引用指向子类

//this相当于s,
return this.name.equals(s.name) && this.age == s.age;
