java gui编程写atm机界面并且实现存储，取款等功能

好的，下面是一个Java GUI程序，实现了ATM机界面，并且实现了存储和取款功能：

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

public class ATMGUI extends JFrame implements ActionListener{
    private JLabel welcomeLabel;
    private JLabel idLabel;
    private JLabel passwordLabel;
    private JTextField idField;
    private JPasswordField passwordField;
    private JButton loginButton;
    private JButton cancelButton;
    private JLabel balanceLabel;
    private JLabel operationLabel;
    private JTextField operationField;
    private JButton depositButton;
    private JButton withdrawButton;
    private double balance;

    public ATMGUI() {
        init();
        this.setTitle("ATM机界面");
        this.setSize(400, 300);
        this.setLocationRelativeTo(null);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        this.setVisible(true);
    }

    public void init() {
        // 欢迎语
        welcomeLabel = new JLabel("欢迎使用ATM机");
        welcomeLabel.setFont(new Font("微软雅黑", Font.BOLD, 24));
        welcomeLabel.setHorizontalAlignment(SwingConstants.CENTER);

        // 用户名和密码输入框
        idLabel = new JLabel("账号：");
        passwordLabel = new JLabel("密码：");
        idField = new JTextField(20);
        passwordField = new JPasswordField(20);

        // 登录和取消按钮
        loginButton = new JButton("登录");
        cancelButton = new JButton("取消");
        loginButton.addActionListener(this);
        cancelButton.addActionListener(this);

        // 余额信息
        balanceLabel = new JLabel("余额：0.0元");
        balanceLabel.setFont(new Font("微软雅黑", Font.BOLD, 16));
        balanceLabel.setHorizontalAlignment(SwingConstants.CENTER);

        // 存款和取款按钮
        operationLabel = new JLabel("请输入操作金额：");
        operationField = new JTextField(20);
        depositButton = new JButton("存款");
        withdrawButton = new JButton("取款");
        depositButton.addActionListener(this);
        withdrawButton.addActionListener(this);

        // 设置布局
        this.setLayout(new GridLayout(6, 2, 10, 10));
        this.add(welcomeLabel);
        this.add(new JLabel(""));
        this.add(idLabel);
        this.add(idField);
        this.add(passwordLabel);
        this.add(passwordField);
        this.add(loginButton);
        this.add(cancelButton);
        this.add(balanceLabel);
        this.add(new JLabel(""));
        this.add(operationLabel);
        this.add(operationField);
        this.add(depositButton);
        this.add(withdrawButton);
    }

    public void actionPerformed(ActionEvent e) {
        if (e.getSource() == loginButton) {
            // 登录
            String id = idField.getText();
            String password = new String(passwordField.getPassword());
            if (id.equals("123456") && password.equals("123456")) {
                JOptionPane.showMessageDialog(this, "登录成功", "提示", JOptionPane.INFORMATION_MESSAGE);
                balance = 1000.0;
                balanceLabel.setText("余额：" + balance + "元");
                idField.setEditable(false);
                passwordField.setEditable(false);
                loginButton.setEnabled(false);
                cancelButton.setText("退出");
            } else {
                JOptionPane.showMessageDialog(this, "账号或密码错误", "错误", JOptionPane.ERROR_MESSAGE);
            }
        } else if (e.getSource() == cancelButton) {
            // 取消或退出
            if (cancelButton.getText().equals("取消")) {
                idField.setText("");
                passwordField.setText("");
            } else {
                System.exit(0);
            }
        } else if (e.getSource() == depositButton) {
            // 存款
            String str = operationField.getText();
            if (str.equals("")) {
                JOptionPane.showMessageDialog(this, "请输入操作金额", "错误", JOptionPane.ERROR_MESSAGE);
            } else {
                double amount = Double.parseDouble(str);
                balance += amount;
                balanceLabel.setText("余额：" + balance + "元");
                operationField.setText("");
                JOptionPane.showMessageDialog(this, "存款成功", "提示", JOptionPane.INFORMATION_MESSAGE);
            }
        } else if (e.getSource() == withdrawButton) {
            // 取款
            String str = operationField.getText();
            if (str.equals("")) {
                JOptionPane.showMessageDialog(this, "请输入操作金额", "错误", JOptionPane.ERROR_MESSAGE);
            } else {
                double amount = Double.parseDouble(str);
                if (amount > balance) {
                    JOptionPane.showMessageDialog(this, "余额不足", "错误", JOptionPane.ERROR_MESSAGE);
                } else {
                    balance -= amount;
                    balanceLabel.setText("余额：" + balance + "元");
                    operationField.setText("");
                    JOptionPane.showMessageDialog(this, "取款成功", "提示", JOptionPane.INFORMATION_MESSAGE);
                }
            }
        }
    }

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

这个程序会生成一个ATM机的登录界面，包含一个欢迎语、一个账号输入框、一个密码输入框以及一个登录按钮和一个取消按钮。登录成功后，会显示余额信息以及存款和取款按钮。你可以在代码中进一步完善其他功能。
