First of all, you should be initializing your mazePoints<\/code> array with the static ints you declared:<\/p>\n

public static char[][] mazePoints = new char[mazeHeight][mazeWidth];\n<\/code><\/pre>\n
But you’ll need to mark them static first:<\/p>\n
private static final int mazeHeight = 12;\nprivate static final int mazeWidth = 58;\n<\/code><\/pre>\n
If they aren’t meant to be static, then neither should your mazePoints<\/code> array.<\/p>\n
Next, you should read the file line by line instead of reading the entire thing at once:<\/p>\n
final Scanner scanner = new Scanner(f);\n\nfor (int row = 0; row < mazeHeight && scanner.hasNext(); row++) {\n    final String mazeRow = scanner.next(); \/\/Get the next row from the scanner.\n    mazePoints[row] = mazeRow.toCharArray(); \/\/Convert the row into a char[].\n}\n<\/code><\/pre>\n
You’re done. You have all your points in mazePoints<\/code> now.<\/p>\n
Note<\/strong><\/em> That new Scanner(f).useDelimiter(\"\\\\A\").next();<\/code> 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.<\/p>\n
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.<\/p>\n
for (int y = 0; y < mazeHeight; y++) {\n    for (int x = 0; x < mazeWidth; x++) {\n        Point point = new Point(x, y);\n        \/\/Do whatever with your point...\n    }\n}\n<\/code><\/pre>\n<\/p><\/div>\n
