java处理谜题并解决越界错误

Question

My error Descriptions
我应该从一个文件中读一个单词搜索谜题我的问题我不断得到越界错误。我不知道如何按照文件的规格正确地格式化字谜。拼图的格式通常是这样的： 5
d e v o l
r e d p h
q c h z j
p o a f
v a m n
q t f o x

这是我到目前为止的工作，我觉得我已经从一个文件读下来，但转换成一个单词搜索难题。尤其是不要硬编码单词seaarch拼图的行和列的规格

public static char[][] fill(){
    // Created 2 different scanner one for user input and one to read the file

    Scanner file1 = new Scanner(System.in);
    // created a count to add the keywords
    int count = 0;

    //System.out.print("Please enter a keyword to search for.");
    // Asking user to input a valid file name
    System.out.print("Please enter a valid puzzle file name\nYou will be asked for the same file name again later.");
    String wordFile = file1.nextLine();
    FileReader infile;
    boolean validFile = false;
    // Creating a while loop that will keep asking for a valid file name
    while(!validFile) {
        // Using a try and catch to obtain correct file
        try {
            infile = new FileReader(wordFile);
            file1 = new Scanner(infile);
            validFile = true;
        }
        //ask the user to put a valid file name if they are wrong
        catch(IOException e) {
            System.out.println("Not a valid file name, please enter again!");
            wordFile = file1.nextLine();
        }
    }
    String numbers = file1.nextLine();
    String[] fileArray = numbers.trim().split(" ");

    int rows = Integer.parseInt(fileArray[0]);
    int columns = Integer.parseInt(fileArray[1]);

    char[][] fillThemLetters = new char [rows][columns];


    String letters = file1.nextLine().trim().replace(" ", "");

    char [] condensed =  letters.toCharArray(); 

    for (int i = 0; i < condensed.length; i++) {

        for(int row = 0; row < rows; row++){


            for(int column = 0; column < columns; column++)
            {
                char index = condensed[i];
                fillThemLetters[row][column] = index;
                i++;
            }
        }

    }   
    return fillThemLetters;
}

Answer 1

您的索引越界错误是由以下原因引起的：

for(int column = 0; column < columns; column++)
{
    char index = condensed[i];
    fillThemLetters[row][column] = index;
    i++; // <    - THIS IS WRONG!!!
}

看到那个i++了吗？你无缘无故地从最外层循环递增计数器。让循环处理自己的增量，它已经内置，如下所示：

for (int i = 0; i < condensed.length; i++) {  // < - You already have i++ here!

在解决了这个问题之后，你会遇到更多的问题——你的代码没有做你认为它正在做的事情，但这些都是独立的问题，应该单独发布
