Solution

  • If you are using Java 7+ version you can use try with resources like the below.

        public static void main(String args[]) {
        try (Scanner in = new Scanner(System.in)) {
            System.out.println("Enter a number - ");
            int n = in.nextInt();
            System.out.println("N is " + n);
        }
    }
