You may also try this:

   public int readInt(String msg) {
        int num = 0;
        try {
            System.out.println(msg);
            num = (new Scanner(System.in)).nextInt();
        } catch (InputMismatchException e) {
            System.out.println("Invalid value!");
            num = readInt(msg);
        } 
        return num;
    }
