        int a= s.nextInt();
        System.out.println("using Scanner function get value  "+ a);
        //user can also use library function like this
        java.util.Scanner x = new java.util.Scanner(System.in);
        int t= x.nextInt();
        System.out.println("using import line in program to get value  "+t );
        Random r= new Random();
        int y=r.nextInt(10);
        System.out.println("using * import style to get random value  "+y);
    }
