Posted 01-20-2010 at 04:46 AM by CoderMan

I'm moving my blogging back to my website. It has been fun blogging here, but it is more advantageous to blog at my own domain:

First Java Applet: Logician

Posted 01-19-2010 at 04:57 AM by CoderMan

A question I've pondered a few times, revisited in my recent work in Java, which seems to have a pretty solid exception handling system: How deep do you go in handling exceptions? As I see it, there seems to be a few categories:
