请你使用java语言设计一个简单的酒店信息管理系统具体要求如下： 1可对房间信息进行查看、编辑编辑即更改房间的入住状态初始房间有9间：101、102、103；201、202、203；301、302、303其中103、202、301已经入住 2可对住户信息进行增加、删除、查看、编辑初始住户有三位：张三、李四、王五分别入住了103、202、301 3可对酒店员工信息进行增加、删除、查看、编辑初始员工有

由于要实现界面交互，使用Java Swing库进行开发。

以下是实现代码：

public class HotelManagementSystem extends JFrame implements ActionListener { private JLabel welcomeLabel; private JButton roomButton, guestButton, staffButton; private JPanel mainPanel;

public HotelManagementSystem() {
    // 初始化房间、住户、员工信息
    rooms = new ArrayList<>();
    rooms.add(new Room("101"));
    rooms.add(new Room("102"));
    rooms.add(new Room("103", true));
    rooms.add(new Room("201"));
    rooms.add(new Room("202", true));
    rooms.add(new Room("203"));
    rooms.add(new Room("301", true));
    rooms.add(new Room("302"));
    rooms.add(new Room("303"));
    guests = new ArrayList<>();

    staffs.add(new Staff("马六", "经理", 8000));
    staffs.add(new Staff("钱七", "员工", 5000));
    staffs.add(new Staff("赵八", "员工", 5000));

    // 设置界面元素
    welcomeLabel = new JLabel("欢迎使用酒店信息管理系统！");
