function* startGame() { const answer = yield 'Do you love JavaScript?'; if (answer !== 'yes'){ return "Oh wow... Guess we're gone here"; } return 'JavaScript loves you back'; } const game = startGame(); console.log(); // 如何输出 Do you love JavaScript? console.log(); // 如何输出 JavaScript loves you back;

要输出 "Do you love JavaScript?"，可以调用 `game.next().value`。

要输出 "JavaScript loves you back"，需要在调用 `game.next(answer)` 时将 answer 设置为 'yes'，然后获取返回值，即 `console.log(game.next('yes').value)`。

修改代码，使startGame方法运行到执行getHinder()后回到for(;success;) 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; //随机抽取一个成语 Random random = new Random(); int index = random.nextInt(chengYuList.size()); ChengYu cy = chengYuList.get(index); String currentIdiom = cy.getChengYu(); for(;success;) { System.out.println(hintCount); for (ChengYu chengYu : commonChengYuList) if(chengYu.getChengYu().startsWith((currentIdiom.substring(currentIdiom.length() - 1)))) 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); } else { score++; } if (success) { System.out.println("恭喜您回答正确，得分：" + score); for (ChengYu nextChengYu : fullChengYuList) if(nextChengYu.getChengYu().startsWith((answer.substring(answer.length() - 1)))) currentIdiom=nextChengYu.getChengYu(); } } } scanner.close(); } //给予用户最多3次提示的机会 private int maxHintCount=3; // 最大提示次数 private int hintCount=0; // 当前提示次数 public String getHint(String currentIdiom) { if (hintCount >= maxHintCount) { System.out.println("提示次数已全部用完，请重新开始游戏!"); hintCount=0; return null; // 已经用完所有提示次数，返回null } for (ChengYu idiom : fullChengYuList) { if(hintCount<maxHintCount) { String reminder=idiom.getChengYu(); if (reminder.startsWith(currentIdiom.substring(currentIdiom.length() - 1))) { System.out.println("提示："+reminder); hintCount++; break; } } } return null; }

在 `getHint()` 方法中，当提示次数已经用完时，需要将 `hintCount` 重置为 0，否则在下一轮游戏时，提示次数将被累加上一轮游戏中剩余的提示次数，从而导致提示次数异常。修改后的代码如下：

public String getHint(String currentIdiom) {
    if (hintCount >= maxHintCount) {
        System.out.println("提示次数已全部用完，请重新开始游戏!");
        int hintCount = 0; // 重置 hintCount 为 0
        return null; // 已经用完所有提示次数，返回null
    }
    for (ChengYu idiom : fullChengYuList) {
        if(hintCount<maxHintCount) {
            String reminder=idiom.getChengYu();
            if (reminder.startsWith(currentIdiom.substring(currentIdiom.length() - 1))) {
                System.out.println("提示："+reminder);
                hintCount++;
                break;
            }
        }
    }
    return null;
}

另外，在 `startGame()` 方法中，如果用户回答错误时，需要在调用 `getHint()` 方法后重新进入循环判断。修改后的代码如下：

if (!cy.isCorrectAnswer(answer,commonChengYuList)) {
    System.out.println("回答错误！");
    success = false;
    getHint(currentIdiom);
    continue; // 重新进入循环判断
} else {
    score++;
}

这样，当用户回答错误时，程序会调用 `getHint()` 方法给予提示，并重新进入循环判断，直到用户回答正确或者提示次数用完为止。

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; for (ChengYu cy : chengYuList) { String currentIdiom = cy.getChengYu(); for (ChengYu chengYu : commonChengYuList) if(chengYu.getChengYu().startsWith((currentIdiom.substring(currentIdiom.length() - 1)))) 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) { System.out.println("恭喜您回答正确，得分：" + score); for (ChengYu nextChengYu : fullChengYuList) if(nextChengYu.getChengYu().startsWith((answer.substring(answer.length() - 1)))) currentIdiom=nextChengYu.getChengYu(); } } } scanner.close(); }修改代码，要求回答正确后，系统以我的成语接龙出下一题

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。
