Java图形界面实现两个复数加减乘除

好的，我可以帮您解决这个问题。

首先，我们需要创建一个Java图形界面来获取两个复数的实部和虚部。您可以使用Java Swing来创建这个GUI。

下面是一个简单的GUI示例代码：

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

public class ComplexCalculator extends JFrame implements ActionListener {
    private JLabel real1Label, imaginary1Label, real2Label, imaginary2Label;
    private JTextField real1Field, imaginary1Field, real2Field, imaginary2Field;
    private JButton addButton, subtractButton, multiplyButton, divideButton;
    private JLabel resultLabel;

    public ComplexCalculator() {
        // 设置窗口标题和大小
        setTitle("复数计算器");
        setSize(400, 300);

        // 创建GUI控件并添加到窗口
        JPanel panel = new JPanel(new GridBagLayout());
        GridBagConstraints constraints = new GridBagConstraints();
        constraints.fill = GridBagConstraints.HORIZONTAL;
        constraints.insets = new Insets(5, 5, 5, 5);

        real1Label = new JLabel("第一个复数的实部：");
        constraints.gridx = 0;
        constraints.gridy = 0;
        panel.add(real1Label, constraints);

        real1Field = new JTextField(10);
        constraints.gridx = 1;
        constraints.gridy = 0;
        panel.add(real1Field, constraints);

        imaginary1Label = new JLabel("第一个复数的虚部：");
        constraints.gridx = 0;
        constraints.gridy = 1;
        panel.add(imaginary1Label, constraints);

        imaginary1Field = new JTextField(10);
        constraints.gridx = 1;
        constraints.gridy = 1;
        panel.add(imaginary1Field, constraints);

        real2Label = new JLabel("第二个复数的实部：");
        constraints.gridx = 0;
        constraints.gridy = 2;
        panel.add(real2Label, constraints);

        real2Field = new JTextField(10);
        constraints.gridx = 1;
        constraints.gridy = 2;
        panel.add(real2Field, constraints);

        imaginary2Label = new JLabel("第二个复数的虚部：");
        constraints.gridx = 0;
        constraints.gridy = 3;
        panel.add(imaginary2Label, constraints);

        imaginary2Field = new JTextField(10);
        constraints.gridx = 1;
        constraints.gridy = 3;
        panel.add(imaginary2Field, constraints);

        addButton = new JButton("加");
        addButton.addActionListener(this);
        constraints.gridx = 0;
        constraints.gridy = 4;
        panel.add(addButton, constraints);

        subtractButton = new JButton("减");
        subtractButton.addActionListener(this);
        constraints.gridx = 1;
        constraints.gridy = 4;
        panel.add(subtractButton, constraints);

        multiplyButton = new JButton("乘");
        multiplyButton.addActionListener(this);
        constraints.gridx = 0;
        constraints.gridy = 5;
        panel.add(multiplyButton, constraints);

        divideButton = new JButton("除");
        divideButton.addActionListener(this);
        constraints.gridx = 1;
        constraints.gridy = 5;
        panel.add(divideButton, constraints);

        resultLabel = new JLabel("");
        constraints.gridx = 0;
        constraints.gridy = 6;
        constraints.gridwidth = 2;
        panel.add(resultLabel, constraints);

        add(panel);

        // 设置窗口可见性和关闭操作
        setVisible(true);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public void actionPerformed(ActionEvent e) {
        double real1 = Double.parseDouble(real1Field.getText());
        double imaginary1 = Double.parseDouble(imaginary1Field.getText());
        double real2 = Double.parseDouble(real2Field.getText());
        double imaginary2 = Double.parseDouble(imaginary2Field.getText());

        if (e.getSource() == addButton) {
            ComplexNumber result = ComplexNumber.add(new ComplexNumber(real1, imaginary1), new ComplexNumber(real2, imaginary2));
            resultLabel.setText("结果为：" + result.toString());
        } else if (e.getSource() == subtractButton) {
            ComplexNumber result = ComplexNumber.subtract(new ComplexNumber(real1, imaginary1), new ComplexNumber(real2, imaginary2));
            resultLabel.setText("结果为：" + result.toString());
        } else if (e.getSource() == multiplyButton) {
            ComplexNumber result = ComplexNumber.multiply(new ComplexNumber(real1, imaginary1), new ComplexNumber(real2, imaginary2));
            resultLabel.setText("结果为：" + result.toString());
        } else if (e.getSource() == divideButton) {
            ComplexNumber result = ComplexNumber.divide(new ComplexNumber(real1, imaginary1), new ComplexNumber(real2, imaginary2));
            resultLabel.setText("结果为：" + result.toString());
        }
    }

    public static void main(String[] args) {
        ComplexCalculator calculator = new ComplexCalculator();
    }
}

上述代码创建了一个Java Swing窗口，其中包含四个文本框用于输入两个复数的实部和虚部，以及四个按钮用于执行加、减、乘和除操作。当用户单击这些按钮时，将调用`actionPerformed`方法来执行相应的操作并显示结果。

接下来，您需要实现`ComplexNumber`类来执行复数加减乘除操作。下面是一个示例实现：

public class ComplexNumber {
    private double real;
    private double imaginary;

    public ComplexNumber(double real, double imaginary) {
        this.real = real;
        this.imaginary = imaginary;
    }

    public static ComplexNumber add(ComplexNumber c1, ComplexNumber c2) {
        return new ComplexNumber(c1.real + c2.real, c1.imaginary + c2.imaginary);
    }

    public static ComplexNumber subtract(ComplexNumber c1, ComplexNumber c2) {
        return new ComplexNumber(c1.real - c2.real, c1.imaginary - c2.imaginary);
    }

    public static ComplexNumber multiply(ComplexNumber c1, ComplexNumber c2) {
        double real = c1.real * c2.real - c1.imaginary * c2.imaginary;
        double imaginary = c1.real * c2.imaginary + c1.imaginary * c2.real;
        return new ComplexNumber(real, imaginary);
    }

    public static ComplexNumber divide(ComplexNumber c1, ComplexNumber c2) {
        double denominator = c2.real * c2.real + c2.imaginary * c2.imaginary;
        double real = (c1.real * c2.real + c1.imaginary * c2.imaginary) / denominator;
        double imaginary = (c1.imaginary * c2.real - c1.real * c2.imaginary) / denominator;
        return new ComplexNumber(real, imaginary);
    }

    public String toString() {
        if (imaginary >= 0) {
            return real + "+" + imaginary + "i";
        } else {
            return real + "" + imaginary + "i";
        }
    }
}

上述代码定义了一个`ComplexNumber`类，用于表示复数并执行加、减、乘和除操作。这个类包含一个构造函数和四个静态方法，分别用于执行加、减、乘和除操作。这个类还包含一个`toString`方法，用于将复数转换为字符串表示。

现在，您可以将这两个类组合在一起，创建一个Java应用程序，用于执行复数加减乘除操作。
