Java-Object类的继承和重写

public class TestObject {
public static void main(String[] args){
   TestObject to = new TestObject();
   System.out.println(to.toString());
   
   Person2 p2= new Person2("李寻欢",30);
   System.out.println(p2.toString());
}
public String toString(){
   return "测试Object对象";
}
}   
class Person2{
String name;
int age;
@Override
public String toString(){
	return name+"年龄："+age;}

public Person2(String name,int age){
	this.name=name;
	this.age=age;
}
}
