写一个Java猜字小游戏，有窗口

当然可以！下面是一个简单的Java猜字小游戏，使用了窗口来进行交互：

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

public class GuessNumberGame extends JFrame {
    private int randomNumber;
    private int guessCount;

    private JTextField inputField;
    private JTextArea outputArea;

    public GuessNumberGame() {
        setTitle("猜字游戏");
        setSize(300, 200);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setLocationRelativeTo(null);

        inputField = new JTextField();
        outputArea = new JTextArea();
        outputArea.setEditable(false);

        JButton guessButton = new JButton("猜");
        guessButton.addActionListener(new GuessButtonListener());

        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        panel.add(inputField, BorderLayout.CENTER);
        panel.add(guessButton, BorderLayout.EAST);

        Container container = getContentPane();
        container.add(panel, BorderLayout.NORTH);
        container.add(new JScrollPane(outputArea), BorderLayout.CENTER);

        randomNumber = generateRandomNumber();
        guessCount = 0;

        outputArea.append("猜一个1到100之间的数字\n");

        setVisible(true);
    }

    private int generateRandomNumber() {
        Random random = new Random();
        return random.nextInt(100) + 1;
    }

    private class GuessButtonListener implements ActionListener {
        @Override
        public void actionPerformed(ActionEvent e) {
            try {
                int guess = Integer.parseInt(inputField.getText());
                guessCount++;

                if (guess < randomNumber) {
                    outputArea.append(guess + " 太小了\n");
                } else if (guess > randomNumber) {
                    outputArea.append(guess + " 太大了\n");
                } else {
                    outputArea.append("恭喜你，猜对了！你一共猜了 " + guessCount + " 次\n");
                    inputField.setEnabled(false);
                    ((JButton) e.getSource()).setEnabled(false);
                }

                inputField.setText("");
                inputField.requestFocus();
            } catch (NumberFormatException ex) {
                outputArea.append("请输入一个有效的数字\n");
            }
        }
    }

    public static void main(String[] args) {
        SwingUtilities.invokeLater(GuessNumberGame::new);
    }
}

这个游戏会生成一个1到100之间的随机数，你需要通过输入猜测的数字来猜出正确的答案。游戏会根据你的猜测给出提示，直到猜对为止。祝你好运！
