Don't call next() so much times! It actually go to the next element when you call it. If you need to use it more than once, put it inside a variable and use it.

        String next = file.next();
        for(int counter = 0 ; counter < next.length(); counter ++) {
            System.out.println(next.charAt(counter));    
        }
