JAVA program to check please answer
-
Simple Java program to check whether input value is numeric or alphabet. If alphabet check whether its Capital or or lowwer case. If digit throw user defined exception " Digit not allowed."
Yes, that is simple. So much so it would be insulting if we offered any help you did not ask for. :)

If digit throw user defined exception " Digit not allowed." Actually m new this forum and New to java. Can you please tell me the solution. will be thank full to you. Can this program be written in command line form? Means if we run it from a command prompt. or in AWT only.? Sorry if any mistake from my side.

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

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.

I mean to say that m asking for the solution as m new to java. and m sorry the way i asked question . Actually the question is write simple program.
If you haven't guessed, no one will write your code, but we'll help you make it right.

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; }

Technically, yes, but using exceptions in such a fashion could be costly.
