Question

I’m trying to read a text file that contains integers and store them into a 2d array.
The problem is splitting.
I can read:

0 0 0
0 1 0
0 0 0

just fine and any numbers 0-9 but I have numbers exceeding 9 (10, 100, 1000).
My method:

int[][] mapArray = new int[11][8];
    AndroidFileIO file = new AndroidFileIO(context.getAssets());
    InputStream is = null;
    try {
        is = file.readAsset("maps/map.txt");
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
        Log.d("android", "could not load file");
    }
    Scanner scanner = new Scanner(is);
    scanner.useDelimiter(",");
    for (int i = 0; i < 11; i++) {
        for (int j = 0; j < 8; j++) {
            mapArray[i][j] = scanner.nextInt();
            Log.d("android", "" + mapArray[i][j]);
        }
    }

So I tried using a delimiter and not it hangs and tells me i’m getting a type mismatch?
Any solutions on splitting integers when reading files?

Answer 1

Figured out to use this as my delimiter:

    scanner.useDelimiter("[\\s,\r\n]+");
