    Default It doesn't detect my file

    I'm making a file that fills a grid of characters, but it doesn't detect the file.

        String map;
        String texture;
        Scanner asdf;
        int rows;
        int cols;
        char Map[][];
        public Map()
        {
     
        }
     
        public Map(String map)
        {
            System.out.println("Finding map....");
            loadGrid(map);
            System.out.println("Map Loaded");
            if (texture == "" || texture == null) {
                System.out.println("Texture not found...");
     
            }
            else System.out.println("Texture Loaded.");
     
        }
     
     
        //loads the grid
        public void loadGrid(String map)
        {
     
                asdf = new Scanner(map);
     
            rows = asdf.nextInt();
            cols = asdf.nextInt();
            Map = new char[rows][cols];
            for (int i = 0; i < rows; i++) {
                String a = asdf.nextLine();
                for (int j = 0; j < cols; j++) {
                    Map[i][j]=a.charAt(j);
                }
            }
     
        }
     
        //prints the characters making up the map
     
     
            public void print()
        {
            for (int i = 0; i < Map.length; i++) {
                for (int j = 0; j < Map[i].length; j++) {
                    System.out.print(Map[i][j] + " ");
                }
                System.out.println("");
            }
        }

    And it keeps giving me this error:


    run:
    Map initialized
    Exception in thread "main" java.util.InputMismatchException
    at java.util.Scanner.throwFor(Scanner.java:909)
    at java.util.Scanner.next(Scanner.java:1530)
    at java.util.Scanner.nextInt(Scanner.java:2160)
    at java.util.Scanner.nextInt(Scanner.java:2119)
    at xavi.Map.loadGrid(Map.java:49)
    at xavi.Xavi.main(Xavi.java:17)
    Java Result: 1
    If anyone knows what my problem is I'd greatly appreciate the help... :/

    Default Re: It doesn't detect my file

    InputMismatchException: The file is being found and read, but that data in the file does not match the type expected by Scanner. Add some print statements to see what is being read from the file to see why there is a data type mismatch.
