李四Employee

package diy.lisi;

import java.time.LocalDate;

public class Employee {
    private final int age; // 年龄: 一般是个人隐私
    public final String name; // 姓名: 姓名通常是公开且不变的
    final LocalDate hireDay = LocalDate.now(); // 入职日期内部可以知道

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

    // ...

    public static void main(String[] args) {
        Employee e = new Employee(18, "张三");
        System.out.println(e.age); // => 18
        System.out.println(e.name); // => 张三
        System.out.println(e.hireDay); // => 2024-10-20
    }
}

李四MyTest

package diy.lisi;

public class MyTest {
    public static void main(String[] args) {
        Employee e = new Employee(18, "张三");
        System.out.println(e.name); // => 张三
        System.out.println(e.hireDay); // => 2024-10-20
//        System.out.println(e.age);
    }
}

diy.MyTest

package diy;

import diy.lisi.Employee;

public class MyTest {
    public static void main(String[] args) {
        Employee e = new Employee(18, "张三");
        System.out.println(e.name); // => 张三
//        System.out.println(e.age);
//        System.out.println(e.hireDay);
    }
}

要求

• 能解释两个MyTest中为什么访问不了相应的字段？并给出可能的解决方法
• 在Employee类中添加公开的访问器，使得在三个main方法中都能顺利读取所有字段值
