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; } } if(label) { currentChengYu=null; System.out.println("无法继续接龙"); break; } } } 其中answer是用户回答的成语,currentchengYu是程序会输出的当前成语,要求接着用户的成语接龙输出currentChengYu.getChengYu()

好的,根据您的要求,我来解释一下这段代码的作用。这段代码是实现了一个成语接龙游戏的功能,其中 `answer` 为用户回答的成语,`currentChengYu` 为程序当前输出的成语。程序会判断用户回答的成语是否符合接龙规则,即以上一个成语的最后一个字作为开头字,如果符合规则则在成语列表 `fullChengYuList` 中查找下一个可以接龙的成语,并将其设置为当前成语 `currentChengYu`,同时输出该成语。如果无法找到可以接龙的成语,则输出“无法继续接龙”,并将当前成语 `currentChengYu` 设置为 `null`,从而结束游戏。

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。
