    I don't know how to return a scanner object. See below a portion of my code.

    CODE

    public class MarkEntry {

    public final int LEN = 200;

    private String[] studNos; // Array for stroing student No's or ID's
    private int[] studScores; // Array for storing the results
    private int nStudents;

    Scanner console = new Scanner(System.in);
    public MarkEntry() {

    int[] studScores = new int [LEN];
    String[] studNos = new String [LEN];
    nStudents = 0;

    }

    // This method repeatedly prompts user to enter a filename until user enters a valid filename.
    // Once a valid filename is entered, this method returns a Scanner object created from the file.
    // The parameter msg is used to construct the propmpt message by: "Enter " + msg + "filename: ".
    // So if msg contains the string student list, then the prompt message would be: ?Enter student list filename:

    Scanner getFileName(String msg)throws FileNotFoundException {


    boolean valid = false;
    Scanner scan = new Scanner (System.in);

    String name = "";
    while (true)
    {
    try {
    System.out.print ("Enter file name: ");
    System.out.flush();
    name = scan.nextLine();
    if (name == "student list")
    name = "slist";
    Scanner fin = new Scanner (new File(name));
    break;
    }
    catch (FileNotFoundException e){
    System.out.println("File not found try again:");
    }

    return
    }
    END CODE

    The return statement above is my problem
