try and catch statements

right now with the code below, I can enter in a negative quantity and the try statement will succeed. If I enter in letters for numbers, for example, the try statement won't succeed, and the catch statement will be displayed. I also want to make the try statement not to succeed and the catch statement to trigger if I enter in a negative quantity. any idea how to do this?

Code:

---

try{
            // create Scanner to read keyboard
          Scanner sc = new Scanner( System.in );
         
          // get title
          System.out.print("Enter title: ");
          String t = sc.nextLine();
         
          // get quantity
          System.out.print("Enter quantity: ");
          int q = sc.nextInt();
}

  catch( InputMismatchException e ){
            System.out.println( "Input error... try again!" );
        }

---

Code:

---

          int q = sc.nextInt();
          if (q < 0) throw new InputMismatchException();

---

Can't say I like the style much, though.

Yes Gary, I don't like that way too. But it's easiest way, than validating and looping conditions again and again, isn't it?

Thank you for the help :)

You are welcome, and thanks for marking the thread solved. :)
