java图形用户登录界面微信登录界面

以下是使用Java Swing实现的简单的图形用户登录界面和微信登录界面的示例代码：

用户登录界面：

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

public class LoginFrame extends JFrame implements ActionListener {
    private JTextField usernameField;
    private JPasswordField passwordField;

    public LoginFrame() {
        setTitle("用户登录");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 200);

        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());

        JPanel inputPanel = new JPanel();
        inputPanel.setLayout(new GridLayout(2, 2));
        inputPanel.add(new JLabel("用户名："));
        usernameField = new JTextField();
        inputPanel.add(usernameField);
        inputPanel.add(new JLabel("密码："));
        passwordField = new JPasswordField();
        inputPanel.add(passwordField);

        contentPane.add(inputPanel, BorderLayout.CENTER);

        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new FlowLayout());
        JButton loginButton = new JButton("登录");
        loginButton.addActionListener(this);
        buttonPanel.add(loginButton);
        JButton cancelButton = new JButton("取消");
        cancelButton.addActionListener(this);
        buttonPanel.add(cancelButton);

        contentPane.add(buttonPanel, BorderLayout.SOUTH);
    }

    public void actionPerformed(ActionEvent event) {
        String command = event.getActionCommand();
        if (command.equals("登录")) {
            String username = usernameField.getText();
            String password = new String(passwordField.getPassword());
            if (username.equals("admin") && password.equals("admin")) {
                JOptionPane.showMessageDialog(this, "登录成功！");
            } else {
                JOptionPane.showMessageDialog(this, "用户名或密码错误！");
            }
        } else if (command.equals("取消")) {
            usernameField.setText("");
            passwordField.setText("");
        }
    }

    public static void main(String[] args) {
        LoginFrame frame = new LoginFrame();
        frame.setVisible(true);
    }
}

微信登录界面：

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

public class WeChatLoginFrame extends JFrame implements ActionListener {
    private JTextField accountField;
    private JPasswordField passwordField;

    public WeChatLoginFrame() {
        setTitle("微信登录");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(400, 200);

        Container contentPane = getContentPane();
        contentPane.setLayout(new BorderLayout());

        JPanel inputPanel = new JPanel();
        inputPanel.setLayout(new GridLayout(2, 2));
        inputPanel.add(new JLabel("账号："));
        accountField = new JTextField();
        inputPanel.add(accountField);
        inputPanel.add(new JLabel("密码："));
        passwordField = new JPasswordField();
        inputPanel.add(passwordField);

        contentPane.add(inputPanel, BorderLayout.CENTER);

        JPanel buttonPanel = new JPanel();
        buttonPanel.setLayout(new FlowLayout());
        JButton loginButton = new JButton("登录");
        loginButton.addActionListener(this);
        buttonPanel.add(loginButton);
        JButton cancelButton = new JButton("取消");
        cancelButton.addActionListener(this);
        buttonPanel.add(cancelButton);

        contentPane.add(buttonPanel, BorderLayout.SOUTH);
    }

    public void actionPerformed(ActionEvent event) {
        String command = event.getActionCommand();
        if (command.equals("登录")) {
            String account = accountField.getText();
            String password = new String(passwordField.getPassword());
            if (account.equals("admin") && password.equals("admin")) {
                JOptionPane.showMessageDialog(this, "登录成功！");
            } else {
                JOptionPane.showMessageDialog(this, "账号或密码错误！");
            }
        } else if (command.equals("取消")) {
            accountField.setText("");
            passwordField.setText("");
        }
    }

    public static void main(String[] args) {
        WeChatLoginFrame frame = new WeChatLoginFrame();
        frame.setVisible(true);
    }
}
