			System.out.println("Char: "+ch);			
		}
		catch (IndexOutOfBoundsException e) {
		      ch = 'z';

Nope, there is not. However, if the string input is empty then the charAt method throws the IndexOutOfBoundsException (see the documentation[^]).
What are you trying to do?

im trying to make it loop if the input is not within the range of a-g

then replace while (!input) with while (input < 'a' || input > 'g').
