通过反射访问如下类：类的访问修饰符，类名，构造方法，所有的属性，所有成员方法，调用所有成员方法。

package com.daiinfo.seniorjava.ken5.implement;

import java.io.Serializable;

public class Employee implements Serializable {

private static final long serialVersionUID = 3049633059823371192L;

private String name; // 表示员工的姓名
private int age; // 表示员工的年龄
private Address address;// 表示员工的地址

public Employee(String name, int age, Address address) {// 利用构造方法初始化各个域
    this.name = name;
    this.age = age;
    this.address = address;
}

public String getName() {
    return name;
}

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

public int getAge() {
    return age;
}

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

public Address getAddress() {
    return address;
}

public void setAddress(Address address) {
    this.address = address;
}

@Override
public String toString() {// 重写toString()方法
    StringBuilder sb = new StringBuilder();
    sb.append("姓名：" + name + ", ");
    sb.append("年龄：" + age + "\n");
    sb.append("地址：" + address);
    sb.append(GetTestValue(100));
    return sb.toString();
}
private String GetTestValue(int n) {
    String m = String.valueOf(n);
    return m + "hello";
}}
小白自学的找的了这个题有没有大佬说一下啊
