// 判断回答是否正确 public boolean isCorrectAnswer(String answer) { String lastChar = chengYu.substring(chengYu.length() - 1); String firstChar = answer.substring(0, 1); return lastChar.equals(firstChar); }要求把这段代码改为只要输入的答案首字符的拼音与给定成语的尾字符拼音(不要求音调)相同即为正确)

可以通过引入第三方库,如pinyin4j,来实现将汉字转换为拼音的功能。具体实现如下:
```java
import net.sourceforge.pinyin4j.PinyinHelper;
// 判断回答是否正确(根据首字母拼音判断)
public boolean isCorrectAnswer(String answer) {
String lastChar = chengYu.substring(chengYu.length() - 1);
String lastCharPinyin = PinyinHelper.toHanyuPinyinStringArray(lastChar.charAt(0))[0];
String firstCharPinyin = PinyinHelper.toHanyuPinyinStringArray(answer.charAt(0))[0];
return lastCharPinyin.equalsIgnoreCase(firstCharPinyin);
}
```
这里使用了PinyinHelper类的toHanyuPinyinStringArray方法将汉字转换为拼音,然后再进行比较。注意,这里使用了拼音的equalsIgnoreCase方法,忽略了音调的差异。

//设定简单模式便宜对上即可 public boolean isCorrectAnswerEasy(String answer,List<ChengYu> commonChengYuList) { char lastChar = chengYu.charAt(chengYu.length() - 1); char firstChar = answer.charAt(0); // 获取上一个成语的拼音末尾字母 String[] lastPinyin = PinyinHelper.toHanyuPinyinStringArray(lastChar); // 获取当前输入成语的拼音首字母 String[] inputPinyin = PinyinHelper.toHanyuPinyinStringArray(firstChar); boolean containsAnswer = false; if (inputPinyin.equals(lastPinyin)) { // 拼音相同 for (ChengYu chengYu : commonChengYuList) { if (chengYu.getChengYu().equals(answer)) { containsAnswer = true; break; } } } return containsAnswer; }
这也是一段Java代码,用于检查用户在简单模式下输入的成语是否正确。具体来说,这个代码段中的变量`answer`是用户输入的成语字符串,`commonChengYuList`是一个成语列表。这个方法首先获取上一个成语的最后一个字的拼音末尾字母和当前输入成语的拼音首字母,并判断它们是否相同。如果相同,则遍历成语列表,检查是否包含用户输入的成语。如果包含,将`containsAnswer`变量设为`true`,否则为`false`。最后返回`containsAnswer`变量,表示用户输入的成语是否正确。综上,这段代码主要是用于检查用户在简单模式下输入的成语是否正确。

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。
