System.out.println("现在的得分为：" + score); for (ChengYu nextChengYu : fullChengYuList) { if(nextChengYu.getChengYu().startsWith((answer.substring(answer.length() - 1)))) { //添一段代码，使得无法接龙时，游戏重开 for(ChengYu cy2:fullChengYuList){ if(cy2.getChengYu().startsWith((nextChengYu.getChengYu().substring(nextChengYu.getChengYu().length() - 1)))) {System.out.println("我接的成语为："+nextChengYu.getChengYu()); currentChengYu=nextChengYu; label=false; break; }break; } } }if(label) { currentChengYu=null; System.out.println("无法继续接龙"); } }为何label始终等于true

根据代码的逻辑，如果label一直等于true，说明在fullChengYuList中没有成语以answer的最后一个字作为开头的成语。因此，程序无法找到一个合适的成语来接龙，导致label一直为true，最终输出“无法继续接龙”。建议检查fullChengYuList中是否包含以answer的最后一个字作为开头的成语。

public void startGame() {
Scanner scanner = new Scanner(System.in);
while (true) {
System.out.println("请选择游戏模式（1-娱乐模式，2-困难模式，0-退出）：");
int mode = scanner.nextInt();
if (mode == 0) {
break;
}
List<ChengYu> chengYuList;
if (mode == 1) {
chengYuList = commonChengYuList;
} else {
chengYuList = fullChengYuList;
}
Collections.shuffle(chengYuList); // 打乱顺序
int score = 0;
boolean success = true;
ChengYu currentChengYu = null;
for (ChengYu cy : chengYuList) {
String currentIdiom = cy.getChengYu();
for (ChengYu chengYu : commonChengYuList) {
if(chengYu.getChengYu().startsWith((currentIdiom.substring(currentIdiom.length() - 1)))) {
currentChengYu = chengYu;
break;
}
}
System.out.println("请回答以下成语的下一个成语：" + currentIdiom + "（难度：" + cy.getDifficultyLevel().getName() + "）");
String answer = scanner.next();
if (!cy.isCorrectAnswer(answer,commonChengYuList)) {
System.out.println("回答错误！");
success = false;
getHint(currentIdiom);
continue;
} else {
score++;
if (success) {
for (ChengYu nextChengYu : commonChengYuList) {
if(nextChengYu.getChengYu().startsWith((answer.substring(answer.length() - 1)))) {
currentChengYu = nextChengYu;
break;
}
}
}
}
}
System.out.println("恭喜您回答正确，得分：" + score);
}
scanner.close();
}

修改后的代码中，增加了一个变量currentChengYu，用来记录当前成语，每次回答正确后，都根据当前成语找到下一个成语，并将其赋值给currentChengYu。然后在下一次循环中，输出当前成语，并让用户回答。

ChengYu currentChengYu = null; System.out.println("进入娱乐模式"); chengYuList = commonChengYuList; Collections.shuffle(chengYuList); // 打乱顺序 for (ChengYu cy : chengYuList) { if (currentChengYu == null) { for (ChengYu cy4 : fullChengYuList) { if (cy4.getChengYu() .startsWith((cy.getChengYu().substring(cy.getChengYu().length() - 1)))) { currentChengYu = cy; break; } } } if (currentChengYu != null) { cy = currentChengYu; } currentIdiom = cy.getChengYu(); System.out.println("请回答以下成语的下一个成语：" + currentIdiom); String answer = scanner.next(); if (answer == null) break; if (!cy.isCorrectAnswerEasy(answer, fullChengYuList)) { System.out.println("回答错误！"); success = false; getHint(cy.getChengYu()); currentChengYu = null; if (hintCount >= maxHintCount) { System.out.println("提示次数已全部用完，请重新开始游戏!"); hintCount = 0; break; } else continue; } else { score++; System.out.println("答对加1分"); success = true; } if (success) { boolean label = true; System.out.println("现在的得分为：" + score); for (ChengYu nextChengYu : chengYuList) { if (nextChengYu.getChengYu().startsWith((answer.substring(answer.length() - 1)))) { for (ChengYu cy2 : chengYuList) { if (cy2.getChengYu() .startsWith((nextChengYu.getChengYu() .substring(nextChengYu.getChengYu().length() - 1))) && nextChengYu != currentChengYu) { currentChengYu = nextChengYu; label = false; break; } } ; } } if (label) { currentChengYu = null; System.out.println("无法继续接龙"); continue; } } } if (score == 16) System.out.print("恭喜通关，你真是个小聪明");在这个代码中添加一些java swing库的应用，要求能够实现窗口

可以使用Java Swing库创建一个简单的窗口，并将游戏界面放入其中。以下是一个简单的示例代码：

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JButton;
import java.awt.BorderLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class ChengYuGame extends JFrame implements ActionListener {
    private JPanel gamePanel;
    private JLabel scoreLabel;
    private JButton startButton;
    private int score;

    public ChengYuGame() {
        // 设置窗口标题
        super("成语接龙游戏");

        // 创建游戏面板
        gamePanel = new JPanel();
        gamePanel.setLayout(new BorderLayout());

        // 创建得分标签
        scoreLabel = new JLabel("得分: " + score);
        gamePanel.add(scoreLabel, BorderLayout.NORTH);

        // 创建开始按钮
        startButton = new JButton("开始游戏");
        startButton.addActionListener(this);
        gamePanel.add(startButton, BorderLayout.CENTER);

        // 将游戏面板添加到窗口中
        getContentPane().add(gamePanel);

        // 设置窗口大小和关闭操作
        setSize(400, 300);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    public void actionPerformed(ActionEvent e) {
        // 点击开始按钮后开始游戏
        if (e.getSource() == startButton) {
            playGame();
        }
    }

    private void playGame() {
        // TODO: 添加游戏逻辑
    }

    public static void main(String[] args) {
        // 创建游戏窗口
        ChengYuGame game = new ChengYuGame();
        game.setVisible(true);
    }
}

在这个示例代码中，我们创建了一个`JFrame`窗口，并在其中添加了一个`JPanel`面板作为游戏界面。面板中包含一个得分标签和一个开始按钮。当用户点击开始按钮时，将调用`playGame()`方法开始游戏。我们可以在`playGame()`方法中添加原先的游戏逻辑。在游戏中，我们可以通过更新得分标签来显示当前得分，例如：`scoreLabel.setText("得分: " + score)`。
