java猜数字游戏窗口

以下是一个简单的Java猜数字游戏窗口的实现：

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

public class GuessNumberGame extends JFrame implements ActionListener {
    private static final long serialVersionUID = 1L;
    private int num = -1;
    private int count = 0;
    private JLabel label1, label2;
    private JTextField textField;
    private JButton button;

    public GuessNumberGame() {
        super("Guess Number Game");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(300, 150);
        setLocationRelativeTo(null);

        label1 = new JLabel("Guess a number between 0 and 100:");
        label2 = new JLabel("");
        textField = new JTextField(10);
        button = new JButton("Guess");
        button.addActionListener(this);

        JPanel panel = new JPanel();
        panel.setLayout(new GridLayout(3, 1));
        panel.add(label1);
        panel.add(textField);
        panel.add(button);
        panel.add(label2);

        setContentPane(panel);
        setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {
        if (num == -1) {
            num = (int) (Math.random() * 100);
        }
        try {
            int guess = Integer.parseInt(textField.getText());
            count++;
            if (guess == num) {
                label2.setText("Congratulations! You guessed the number in " + count + " tries.");
                button.setEnabled(false);
            } else if (guess < num) {
                label2.setText("Too low. Try again.");
            } else {
                label2.setText("Too high. Try again.");
            }
        } catch (NumberFormatException ex) {
            label2.setText("Invalid input. Please enter an integer between 0 and 100.");
        }
    }
}

这个程序实现了一个简单的猜数字游戏窗口，用户需要在文本框中输入一个0到100之间的整数，然后点击“Guess”按钮进行猜测。程序会根据用户的猜测给出相应的提示，直到用户猜中为止。
