      while(true) {
         try {
 
            System.out.print("Enter Positive Number: ");
            int i = sc.nextInt();
            if(i > 0){
               System.out.println("You entered: " + i);
               System.out.println("Thank you");
               break;
            } else {
               System.out.println("Negative Number");
            }
 
         } catch (InputMismatchException e) {
            System.out.println("You did not enter a Number.");
