只用AWT写以下代码package chap03; import javax.swing.; import java.awt.; import java.awt.event.*; public class GuessNumber extends JFrame implements ActionListener { private JLabel promptLabel, resultLabel; private JTextField inputField; private JButton guessButton, exitButton; private int targetNumber, guessCount, maxTryTime; public GuessNumber () { targetNumber = (int)(Math.random()*10)+1; guessCount = 0; maxTryTime = 5; promptLabel = new JLabel("请输入一个0~10之间的数字："); inputField = new JTextField(10); guessButton = new JButton("猜！"); guessButton.addActionListener(this); exitButton = new JButton("退出"); exitButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { System.exit(0); } }); resultLabel = new JLabel(""); JPanel panel = new JPanel(); panel.add(promptLabel); panel.add(inputField); panel.add(guessButton); panel.add(exitButton); panel.add(resultLabel); this.add(panel); this.setTitle("猜数字游戏界面"); this.setSize(300, 150); this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setVisible(true); } public void actionPerformed(ActionEvent e) { String inputText = inputField.getText(); try { int guessNumber = Integer.parseInt(inputText); guessCount++; if (guessCount < maxTryTime) { int c = maxTryTime - guessCount; if (guessNumber > targetNumber) { resultLabel.setText("输入的过大，您还有" + c + "次机会"); } else if (guessNumber < targetNumber) { resultLabel.setText("输入的过小，您还有" + c + "次机会"); } else { resultLabel.setText("恭喜你，猜对了！你一共猜了" + guessCount + "次"); guessButton.setEnabled(false); } } else { resultLabel.setText("抱歉游戏失败"); guessButton.setEnabled(false); } } catch (NumberFormatException ex) { resultLabel.setText("输入异常，请重新输入!!!"); } } public static void main(String[] args) { new GuessNumber(); } }运行时能给文字足够的显示空间

好的，以下是使用AWT重写的代码，确保给予足够的显示空间：

    private Label promptLabel, resultLabel;

        targetNumber = (int)(Math.random()*10)+1;
        guessCount = 0;
        maxTryTime = 5;

        promptLabel = new Label("请输入一个0~10之间的数字：");
        inputField = new TextField(10);
        guessButton = new Button("猜！");
        guessButton.addActionListener(this);
        exitButton = new Button("退出");
        exitButton.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                System.exit(0);
            }
        });
        resultLabel = new Label("");

        Panel panel = new Panel();
        panel.setLayout(new GridLayout(3, 2, 5, 5));

        panel.add(promptLabel);
        panel.add(inputField);
        panel.add(guessButton);

        // 保证文字能够完全显示
        this.setMinimumSize(new Dimension(300, 150));
        this.setMaximumSize(new Dimension(600, 300));

        this.addWindowListener(new WindowAdapter() {
            public void windowClosing(WindowEvent e) {
                System.exit(0);
            }
        });

        this.setVisible(true);
    }

    public void actionPerformed(ActionEvent e) {

            guessCount++;

            if (guessCount < maxTryTime) {
                int c = maxTryTime - guessCount;
                if (guessNumber > targetNumber) {
                    resultLabel.setText("输入的过大，您还有" + c + "次机会");
                } else if (guessNumber < targetNumber) {
                    resultLabel.setText("输入的过小，您还有" + c + "次机会");
                } else {
                    resultLabel.setText("恭喜你，猜对了！你一共猜了" + guessCount + "次");
                    guessButton.setEnabled(false);
                }
            } else {
                resultLabel.setText("抱歉游戏失败");
                guessButton.setEnabled(false);
            }
        } catch (NumberFormatException ex) {
            resultLabel.setText("输入异常，请重新输入!!!");
        }
    }

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