       System.out.println("Enter input number ");

       Scanner sc = new Scanner(System.in);

       int inputNumber = sc.nextInt();        

       int sqrtNum = (int) Math.sqrt(inputNumber);

       int product = sqrtNum * (sqrtNum + 1);

       if (product == inputNumber)

           System.out.println("Pronic Number");

       else

           System.out.println("Not a Pronic Number")
