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。
