[Solved] How to traverse java maze using stacks

First of all, you should be initializing your mazePoints array with the static ints you declared:

public static char[][] mazePoints = new char[mazeHeight][mazeWidth];

But you’ll need to mark them static first:

private static final int mazeHeight = 12;
private static final int mazeWidth = 58;

If they aren’t meant to be static, then neither should your mazePoints array.

Next, you should read the file line by line instead of reading the entire thing at once:

final Scanner scanner = new Scanner(f);

for (int row = 0; row < mazeHeight && scanner.hasNext(); row++) {
    final String mazeRow = scanner.next(); //Get the next row from the scanner.
    mazePoints[row] = mazeRow.toCharArray(); //Convert the row into a char[].
}

You’re done. You have all your points in mazePoints now.

Note That new Scanner(f).useDelimiter("\\A").next(); that you were using was just changing the default delimiter so that it read the entire file at once. You don’t want that behavior. Use the default behavior which reads a line at a time.

You can blindly traverse the entire 2D array as follows, though, you probably need to implement some type of algorithm rather than iterating the entire 2D array.

for (int y = 0; y < mazeHeight; y++) {
    for (int x = 0; x < mazeWidth; x++) {
        Point point = new Point(x, y);
        //Do whatever with your point...
    }
}
