    Do you mean that you could code this with your eyes closed, or you are throwing down a challenge to the rest of us?

    Just say 'NO' to evaluated arguments for diadic functions! Ash

      Yes, that is simple. So much so it would be insulting if we offered any help you did not ask for. :)

              Unfortunately no, you need to work it out for yourself. If you are new to Java then I suggest you spend time working through these tutorials[^]. There is a high probability that you will find the answer quite easily.

                    OK, that's much better. This is a question we are willing to answer. If alphabet check whether its Capital or or lowwer case check this: java.lang.String @ oracle.com and - as you want to find capital letters check this ASCII-Table the "HTML" and the "chr" columns are quite interesting when combined with java.lang.Character @ oracle.com If digit throw user defined exception " Digit not allowed." check this: Try Catch Tutorial @ oracle.com and find a way to convert a String into a java.lang.Integer @ oracle.com ;) regards Torsten

                      is this program right to check whether string is alpha or numeric public boolean isIntNumber(String num){ try{ Integer.parseInt(num); } catch (NumberFormatException nfe) { return false; } return true; }

                        Well it's certainly one of doing it. What happens when you run this code passing in a string, number, null etc.?

                          well, it is just one method - not a complete program - but it will do what it is suposed to do. regards Torsten
