java - 从另一个类向 ArrayList 添加元素

Question

我只有这个基本代码，我需要帮助将员工数据添加到另一个类的 ArrayList 中。我只是为了准备作业而编写这段代码，所以不要过多地批评我的代码。但本质上，我需要添加员工元素并最终删除它们。但现在，我只需要帮助将元素添加到我的其他 Employee 类中。 =]

public class main {
    private static Employee employee;   

    public static void main(String[] args) {
        employee = new Employee(10,10); 
        System.out.println(employee.toString());
    }
}

............

import java.util.ArrayList;

public class Employee {
    public int employeeNum;
    public double hourRate;
    ArrayList<Employee> Employee = new ArrayList<>();

    public Employee(int employeeNum, double hourRate){
        this.employeeNum = employeeNum;
        this.hourRate = hourRate;
    }

    public String toString(){
        return ""+employeeNum+hourRate;
    }
}

简单示例 -

package com;

import java.util.ArrayList;

public class TestPage{

    public static void main(String[] args){
        Employee emp1, emp2;

        emp1 = new Employee();
        emp2 = new Employee();

        emp1.setName("MAK");
        emp2.setName("MICHELE");

        emp1.setAddress("NY");
        emp2.setAddress("WY");

        //and keep putting other information like this

        ArrayList<Employee> employee = new ArrayList<Employee>();
        employee.add(emp1);
        employee.add(emp2);

        System.out.println("emp1 name is : " + employee.get(0).getName());
        System.out.println("emp2 name is : " + employee.get(1).getName());

        System.out.println("emp1 address is : " + employee.get(0).getAddress());
        System.out.println("emp2 address is : " + employee.get(1).getAddress());
    }
}

class Employee{
    String name, address;
    int age, salary;

    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getAddress() {
        return address;
    }
    public void setAddress(String address) {
        this.address = address;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public int getSalary() {
        return salary;
    }
    public void setSalary(int salary) {
        this.salary = salary;
    }
}
