    Default Scanner Class

    Need help writing a method that repeatedly prompts the user for the name of an input file until the user enters
    the name of an existing file; then creates and returns a Scanner for the input file. Also how to create a try/catch block that handles FileNotFoundException.

    //Repeatedly prompts the user for the name of an input file until the user enters
    //the name of an existing file; then creates and returns a Scanner for the input file.
    //See the lecture notes for your section and/or the textbook for examples.
    //Use a try/catch block to catch and handle any FileNotFoundException's that occur
    public static Scanner getInputScanner(Scanner console){
    Scanner result = null;
    while (result == null) {
    System.out.print("input file name? ");
    String name = console.next();
    try {
    result = new Scanner(new File(name));
    }
    catch (FileNotFoundException e) {

    }
    }
    return result;
    }

    This is my code thus far.
