嗨，我上大学时必须在这里做的小型 Java 项目。这是我到目前为止所拥有的。我不明白为什么它不编译。我编写了用于生成网格的代码；网格尺寸由输入词设置（所有输入词的字母总和 * 1.5）。我不确定将数组列表的所有元素加在一起的部分。

这是怎么回事？提前致谢 ：）

我可以看到多个问题：

在类声明行中不应有分号。

public class WordSearchPuzzle

正如 Nettogrof 所示，您的方法中有太多 } createPuzzleGrid。

其中的循环createPuzzleGrid使用不存在的方法。没有size为数组列表提供参数的方法。它也没有找到那个点的字符串长度你的循环createPuzzleGrid应该是：

for (int i = 0; i < puzzleWords.size; i++) {
    String item = puzzleWords.get(i);
    int itemLength = item.length();
    letterCount = letterCount + itemLength;
}

作为额外说明，该方法的最后一行访问puzzle数组但不执行任何操作，因此可以删除此行。事实上，没有任何方法使用该puzzle变量，因此可以将其完全删除。

去掉这里的分号.... public class WordSearchPuzzle;

这不是一个声明。 puzzle[gridDimensions][gridDimensions];

puzzleWords.size(i).length在 for 循环中给出了问题。如果您想要列表中的元素数量，puzzleWords.size()它将起作用。然后 letterCount = puzzleWords + letterCount ; ，你有不兼容的类型，ArrayList + int，你是要使用puzzleWords.size()而不是puzzleWords吗？

在您的 createPuzzleGrid 中，您的 For 循环中有两个 }

正确的版本：

private void createPuzzleGrid()
{
  int i;
    for(i = 0; i < puzzleWords.size(i).length ; i++){
      letterCount = puzzleWords + letterCount ;
    }
    gridDimensions = letterCount * 1.5;
    puzzle[gridDimensions][gridDimensions];
}
