JAVA 设计Manager类、GUI类及事件处理 (1)设计一个Manager类并编写代码， Manager类的属性有姓名，工号，基本工资，小时工资(元/小时）。自定义方法：至少包括计算月工资的方法：calSalary()。 (2)编写一个GUI类，输入manager的姓名、工号，基本工资，月工作时间（小时），创建对象，调用calSalary()方法计算出该manager的月工资，并显示在用户界面上。

好的，我会根据您的要求进行解答。下面是代码实现：

Manager.java

public class Manager {
    private String name;
    private String id;
    private double basicSalary;
    private double hourSalary;

    public Manager(String name, String id, double basicSalary, double hourSalary) {
        this.name = name;
        this.id = id;
        this.basicSalary = basicSalary;
        this.hourSalary = hourSalary;
    }

    public double calSalary(double workHours) {
        return basicSalary + workHours * hourSalary;
    }

    public String getName() {
        return name;
    }

    public String getId() {
        return id;
    }

    public double getBasicSalary() {
        return basicSalary;
    }

    public double getHourSalary() {
        return hourSalary;
    }
}

GUI.java

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class GUI extends JFrame implements ActionListener {
    private JLabel nameLabel;
    private JLabel idLabel;
    private JLabel basicSalaryLabel;
    private JLabel workHoursLabel;
    private JLabel salaryLabel;
    private JTextField nameField;
    private JTextField idField;
    private JTextField basicSalaryField;
    private JTextField workHoursField;
    private JButton calButton;
    private Manager manager;

    public GUI() {
        setTitle("Manager");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLayout(new GridLayout(5, 2));

        nameLabel = new JLabel("Name:");
        idLabel = new JLabel("ID:");
        basicSalaryLabel = new JLabel("Basic Salary:");
        workHoursLabel = new JLabel("Work Hours:");
        salaryLabel = new JLabel("Salary:");

        nameField = new JTextField(10);
        idField = new JTextField(10);
        basicSalaryField = new JTextField(10);
        workHoursField = new JTextField(10);

        calButton = new JButton("Calculate Salary");
        calButton.addActionListener(this);

        add(nameLabel);
        add(nameField);
        add(idLabel);
        add(idField);
        add(basicSalaryLabel);
        add(basicSalaryField);
        add(workHoursLabel);
        add(workHoursField);
        add(calButton);
        add(salaryLabel);

        setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        String name = nameField.getText();
        String id = idField.getText();
        double basicSalary = Double.parseDouble(basicSalaryField.getText());
        double workHours = Double.parseDouble(workHoursField.getText());

        manager = new Manager(name, id, basicSalary, 50);
        double salary = manager.calSalary(workHours);

        salaryLabel.setText("Salary: " + salary);
    }

    public static void main(String[] args) {
        new GUI();
    }
}

上述代码实现了一个简单的 GUI 界面，用户可以输入经理的姓名、工号、基本工资和月工作时间，然后调用 Manager 类的 calSalary() 方法计算月工资并将结果显示在界面上。
