java中的Object类的toSpring()方法

package com.itheima_56;

public class Student extends Object{
private String name;
private int age;

public Student(){
}

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

}

public void setName(String name) {
this.name = name;
}

public int getAge() {
return age;
}

public void setAge(int age) {
this.age = age;
}

//重写toString方法
@Override
public String toString() {
return "Student{" +
"name='" + name + '\'' +
", age=" + age +
'}';
}
}

package com.itheima_56;


public class ObjectDemo {

System.out.println(s);//默认com.itheima_56.Student@5cad8086
