Howdy, hoping this is an easy question, but I'm taking a String and cutting out the characters one by one, and I want to test if the character is an kind of number, I'm just not sure how to go about that test.
Thanks.

Hi Kevin,
Here is the sample code. To run this you need to provide the string you want to test as one command line argument : java Ex4 Some23Argument
