Question

For a program I am writing, I need to ask a user for an integer between 1 and 8. I’ve tried multiple (cleaner) ways of doing this but none of them worked, so I’m left with this:

    int x = 0;     while (x < 1 || x > 8)     {            System.out.print('Please enter integer  (1-8): ');          try         {             x = Integer.parseInt(inputScanner.next());         }         catch(NumberFormatException e)         {             x = 0;         }     } 

Where inputScanner is a Scanner. Surely there is a better way?

Answer 1

Scanner does regular expressions, right? Why not check if it matches ‘^[1-8]$’ first?
