Infinite loop on Scanner.hasNext, reading from a file

Question

I\'m apparently facing an infinite loop on while(input.hasNext()) , as in following code

File file = new File(\"data.txt\");
Scanner input = new Sca

You do not need to double checking on content. this should work:

   File file = new File("data.txt");
    Scanner input = new Scanner(file);

    int sum = 0;

    while(input.hasNextInt()) {
            sum += input.nextInt();
    }
    System.out.println(sum);

Hope this helps.
