帮我编写图形界面的Java Application程序，输入两个复数，输出复数之和、差、积和商。程序为两层架构

在Java中，创建一个图形用户界面（GUI）的Java Application程序来处理复数运算通常需要使用Swing或JavaFX库。这里是一个简单的示例，展示如何使用Swing框架来实现这个功能：

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

class ComplexNumber extends JFrame {
    private JTextField realPartAField, imagPartAField, realPartBField, imagPartBField;
    private JTextField sumField, differenceField, productField, quotientField;

    public ComplexNumber() {
        setTitle("复数计算器");
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel inputPanel = new JPanel();
        inputPanel.setLayout(new GridLayout(4, 2));

        JLabel labelRealA = new JLabel("复数A实部:");
        realPartAField = new JTextField();
        JLabel labelImagA = new JLabel("虚部:");
        imagPartAField = new JTextField();

        JLabel labelRealB = new JLabel("复数B实部:");
        realPartBField = new JTextField();
        JLabel labelImagB = new JLabel("虚部:");
        imagPartBField = new JTextField();

        JButton calculateButton = new JButton("计算");

        inputPanel.add(labelRealA);
        inputPanel.add(realPartAField);
        inputPanel.add(labelImagA);
        inputPanel.add(imagPartAField);
        inputPanel.add(labelRealB);
        inputPanel.add(realPartBField);
        inputPanel.add(labelImagB);
        inputPanel.add(imagPartBField);
        inputPanel.add(calculateButton);

        JPanel resultPanel = new JPanel();
        resultPanel.setLayout(new GridLayout(4, 1));

        sumField = new JTextField("0 + 0i");
        differenceField = new JTextField("0 + 0i");
        productField = new JTextField("0 + 0i");
        quotientField = new JTextField("0 + 0i");

        resultPanel.add(new JLabel("和:"));
        resultPanel.add(sumField);
        resultPanel.add(new JLabel("差:"));
        resultPanel.add(differenceField);
        resultPanel.add(new JLabel("积:"));
        resultPanel.add(productField);
        resultPanel.add(new JLabel("商:"));
        resultPanel.add(quotientField);

        JPanel buttonPanel = new JPanel();
        buttonPanel.add(new JLabel("\n"));

        calculateButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent e) {
                double realA = Double.parseDouble(realPartAField.getText());
                double imagA = Double.parseDouble(imagPartAField.getText());
                double realB = Double.parseDouble(realPartBField.getText());
                double imagB = Double.parseDouble(imagPartBField.getText());

                double sumRe = realA + realB;
                double sumIm = imagA + imagB;
                double differenceRe = realA - realB;
                double differenceIm = imagA - imagB;
                double productRe = realA * realB - imagA * imagB;
                double productIm = realA * imagB + imagA * realB;
                double quotientRe = (realA * realB + imagA * imagB) / Math.pow(realB, 2) + imagA * imagB / Math.pow(realB, 2);
                double quotientIm = (imagA * realB - realA * imagB) / Math.pow(realB, 2);

                sumField.setText(String.format("%.2f + %.2fi", sumRe, sumIm));
                differenceField.setText(String.format("%.2f + %.2fi", differenceRe, differenceIm));
                productField.setText(String.format("%.2f + %.2fi", productRe, productIm));
                quotientField.setText(String.format("%.2f + %.2fi", quotientRe, quotientIm));
            }
        });

        setLayout(new BorderLayout());
        add(inputPanel, BorderLayout.NORTH);
        add(resultPanel, BorderLayout.CENTER);
        add(buttonPanel, BorderLayout.SOUTH);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(() -> {
            ComplexNumber complexApp = new ComplexNumber();
            complexApp.setVisible(true);
        });
    }
}

当你运行这个程序，用户可以在文本框中输入复数的实部和虚部，然后点击“计算”按钮，就会看到结果出现在相应的字段中。
