Ok guys so i am trying to read in from 1 out of 3 files normally with out the `if` ... `else` clause 

just `Scanner myScanner = new Scanner(new File("maze1.txt"));` would run the problem, but i want the user to select what maze he/she would like to run

```
public class Main {
    private static Scanner myScanner;

    public static void main(String[] args) throws FileNotFoundException {

        System.out.println("Please Enter 1,2 or 3 to pick the different maze you would like being solved.");
        Scanner myScannerinput = new Scanner(System.in);

        int Mazenumber = myScannerinput.nextInt();

        if(Mazenumber == 1){
            Scanner myScanner = new Scanner(new File("maze1.txt"));
        }
        else if(Mazenumber == 2){
            Scanner myScanner = new Scanner(new File("maze2.txt"));
        }
        else if(Mazenumber == 3){
            Scanner myScanner = new Scanner(new File("maze3.txt"));
        }
        else{
            System.out.println("You did not choose one of the 3 mazes");
        }

        int numRows = myScanner.nextInt();
        int numCols = myScanner.nextInt();
        myScanner.nextLine();

        int startX = 0;
        int startY = 0;'

```

Please Enter 1,2 or 3 to pick the different maze you would like being solved.
