大家好,在制作单词拼图游戏的时候,我遇到了一个双重检查的问题,纵向和横向都是我当前文件中保存为arraylist的单词。
String letterSize = "" + size;
makeLetterWordList(letterSize);
boolean finished = false;
while ( !finished ) {
finished = true;
for (int i = 0; i < size; i++) {
int randomYWord = randomInteger(wordList.size());
String item = wordList.get(randomYWord);
puzzleListY.add(item);
}
for (int i = 0; i <= puzzleListY.size(); i++) {
StringBuilder sb = new StringBuilder();
for (int j = 0; j <= puzzleListY.size(); j++) {
sb.append(puzzleListY.get(j).charAt(j));
}
randomXWord = sb.toString();
if (!wordList.contains(randomXWord)) {
finished = false;
break;
} else {
puzzleListX.add(randomXWord);
}
}
}
产生的错误如下:
Exception in thread "main" java.lang.IndexOutOfBoundsException: Index: 3, Size: 3
at java.util.ArrayList.rangeCheck(ArrayList.java:653)
我很难在我的代码中发现错误,任何人都可以帮助我吗?
答案 0 :(得分:1)
循环应该只有大小 - 1
@Local
public interface AccountServiceLocal {
public void create(Account a);
public void delete(Object id);
public Account find(Object id);
public List<?> findemail(Object id);
public void update(Account a);
}
对于其他循环,因为你从索引0开始并且有n个元素循环应该是从0到n-1
