用java结合图形界面制作一个猜数字游戏

好的，下面是一个简单的猜数字游戏的 Java Swing 实现，您可以根据需要进行修改和扩展：

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

public class GuessingGameGUI extends JFrame {
    private int randomNumber;
    private int guessesLeft;
    private JLabel messageLabel;
    private JTextField guessTextField;
    private JButton guessButton;

    public GuessingGameGUI() {
        randomNumber = (int) (Math.random() * 100) + 1;
        guessesLeft = 5;

        messageLabel = new JLabel("I'm thinking of a number between 1 and 100. You have " + guessesLeft + " guesses left.");
        guessTextField = new JTextField(10);
        guessButton = new JButton("Guess");
        guessButton.addActionListener(new GuessButtonListener());

        JPanel controlPanel = new JPanel();
        controlPanel.add(messageLabel);
        controlPanel.add(guessTextField);
        controlPanel.add(guessButton);

        setLayout(new BorderLayout());
        add(controlPanel, BorderLayout.CENTER);

        setTitle("Guessing Game");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        pack();
        setVisible(true);
    }

    private class GuessButtonListener implements ActionListener {
        public void actionPerformed(ActionEvent event) {
            String guessString = guessTextField.getText();
            int guess = Integer.parseInt(guessString);
            guessesLeft--;

            if (guess == randomNumber) {
                messageLabel.setText("Congratulations! You guessed the number in " + (5 - guessesLeft) + " guesses.");
                guessButton.setEnabled(false);
            } else if (guessesLeft == 0) {
                messageLabel.setText("Sorry, you have used up all your guesses. The number was " + randomNumber + ".");
                guessButton.setEnabled(false);
            } else if (guess < randomNumber) {
                messageLabel.setText("Too low. You have " + guessesLeft + " guesses left.");
            } else {
                messageLabel.setText("Too high. You have " + guessesLeft + " guesses left.");
            }

            guessTextField.setText("");
        }
    }

    public static void main(String[] args) {
        GuessingGameGUI gameGUI = new GuessingGameGUI();
    }
}

在这个界面中，我们使用了一个 randomNumber 变量来存储随机生成的数字，一个 guessesLeft 变量来存储用户剩余的猜测次数。当用户点击 Guess 按钮时，我们获取用户输入的数字，比较它和随机数的大小，并根据结果更新界面显示。如果用户猜对了，我们显示恭喜信息，并禁用 Guess 按钮；如果用户用完了所有的猜测次数，我们显示失败信息，并禁用 Guess 按钮；否则，我们显示剩余猜测次数，并清空用户输入框，等待用户继续猜测。

这只是一个简单的示例，您可以根据需要进行修改和扩展，例如添加更多的界面元素、增加游戏难度、添加计时器等等。
