写一个java的图形界面理发店登陆系统

好的，下面是一个简单的Java图形界面理发店登陆系统的示例代码，其中使用了JFrame、JPanel、JLabel、JTextField、JPasswordField和JButton等组件：

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

public class BarberShopLoginSystem extends JFrame implements ActionListener {
    private JPanel panel;
    private JLabel userLabel, passwordLabel, titleLabel;
    private JTextField userTextField;
    private JPasswordField passwordField;
    private JButton loginButton, resetButton;

    public BarberShopLoginSystem() {
        setTitle("理发店登陆系统");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);

        panel = new JPanel();
        panel.setLayout(null);

        titleLabel = new JLabel("理发店登陆系统");
        titleLabel.setBounds(120, 30, 200, 20);
        panel.add(titleLabel);

        userLabel = new JLabel("用户名:");
        userLabel.setBounds(50, 80, 80, 20);
        panel.add(userLabel);

        userTextField = new JTextField();
        userTextField.setBounds(130, 80, 150, 20);
        panel.add(userTextField);

        passwordLabel = new JLabel("密  码:");
        passwordLabel.setBounds(50, 120, 80, 20);
        panel.add(passwordLabel);

        passwordField = new JPasswordField();
        passwordField.setBounds(130, 120, 150, 20);
        panel.add(passwordField);

        loginButton = new JButton("登  陆");
        loginButton.setBounds(80, 180, 80, 25);
        loginButton.addActionListener(this);
        panel.add(loginButton);

        resetButton = new JButton("重  置");
        resetButton.setBounds(200, 180, 80, 25);
        resetButton.addActionListener(this);
        panel.add(resetButton);

        add(panel);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent ae) {
        if (ae.getSource() == loginButton) {
            String user = userTextField.getText();
            String password = new String(passwordField.getPassword());

            if (user.equals("admin") && password.equals("admin123")) {
                JOptionPane.showMessageDialog(this, "登陆成功！");
            } else {
                JOptionPane.showMessageDialog(this, "用户名或密码错误！");
            }
        } else if (ae.getSource() == resetButton) {
            userTextField.setText("");
            passwordField.setText("");
        }
    }

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

这个登陆系统中，用户需要输入用户名和密码才能登陆系统。如果用户名和密码匹配，系统会弹出一个提示框提示用户登陆成功；否则，弹出提示框提示用户名或密码错误。用户可以点击“重置”按钮清空用户名和密码输入框。
