java鸡兔同笼制作UI界面代码

以下是一个简单的 Java 程序，用于模拟鸡兔同笼问题并在 UI 界面中显示结果：

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

public class ChickenRabbitUI extends JFrame implements ActionListener {
    private JTextField txtHead, txtFoot;
    private JLabel lblResult;

    public ChickenRabbitUI() {
        setTitle("鸡兔同笼");
        setSize(300, 150);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel pnlInput = new JPanel(new GridLayout(2, 2));
        pnlInput.add(new JLabel("头数："));
        txtHead = new JTextField();
        pnlInput.add(txtHead);
        pnlInput.add(new JLabel("脚数："));
        txtFoot = new JTextField();
        pnlInput.add(txtFoot);

        JButton btnCalc = new JButton("计算");
        btnCalc.addActionListener(this);

        lblResult = new JLabel();

        JPanel pnlMain = new JPanel(new BorderLayout());
        pnlMain.add(pnlInput, BorderLayout.CENTER);
        pnlMain.add(btnCalc, BorderLayout.EAST);
        pnlMain.add(lblResult, BorderLayout.SOUTH);

        setContentPane(pnlMain);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        int heads = Integer.parseInt(txtHead.getText());
        int feet = Integer.parseInt(txtFoot.getText());

        int rabbits = (feet - 2 * heads) / 2;
        int chickens = heads - rabbits;

        if (rabbits < 0 || chickens < 0 || (feet - rabbits * 4 - chickens * 2) != 0) {
            lblResult.setText("无解");
        } else {
            lblResult.setText("鸡：" + chickens + "只，兔：" + rabbits + "只");
        }
    }

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

这个程序创建了一个简单的 UI 界面，用于输入鸡和兔的头数和脚数，并在计算按钮被点击时计算鸡和兔的数量，并在界面中显示结果。
