    Default Taking a txt file in and making it a 2d int array

    So I am trying to take a txt file that is laid out like this

    651111111117
    200000000002
    200000000002
    200000000002
    200001000002
    200000000002
    200000000002
    200000000002
    200000000002
    200000000002
    200000000002
    911111111118

    (each 12 numbers are a new line)

    and pull it into a method in java as a 2d integer array with each digit as a new integer. I thought this would work for it but it gave me errors.

    Scanner scan = new Scanner(new File("Filename.txt"));
    int row=0, col=0;

    while (scan.hasNextLine() == true){
    while (scan.hasNextInt() == true ){
    Array[row][col] = scan.nextInt();
    col++;
    }
    row++;
    }

    it gave me errors.
    Please copy the full text of the error message and paste it here. It has important info about the error.


    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
