The class I'm enrolled in is an Intro to Java, so I guess it's basically a tutorial. The book (JAVA: How to Program 7th ed) presents the material in basic syntax that is run from the command line and has input/output there also. The instructor presented a couple of very basic dialog box examples, but the context is a little outside my reasoning so far.

I really appreciate your help. I wasn't aware of the the "checkEven" command and that alone makes a world of difference. I pasted what you presented into my original in JCreator and am still getting a few errors with the error checking that you provided; I'll have to iron that out. I'm sure it's probably declarations on my part again.

Thank you again and have a great day!
