Ok, this is really weird. I wrote some codes a day ago, and then edited the codes. Then after hours and hours of editing and rewriting and introducing new classes, I ran the codes, but then I go a response from a "System.out.println()" line that I had long removed. Basically, netbeans seems to be running a much older build of my codes. I've cleaned and re-built my codes and still nothing. It keeps running old codes.
What's going on?
