Playing MP3 Files

Submitted by Jeff Friesen on Thu, 03/10/2011 - 16:36.

Welcome to Java Tutor

Submitted by Jeff Friesen on Thu, 02/24/2011 - 22:00.
Hello. I'm Jeff Friesen and I welcome you to Java Tutor, a new blog that I'm writing for JavaWorld.

I teach about these technologies mainly via programming projects (e.g., multiple key press detection).

I welcome your input to this blog, and will write about relevant topics that you suggest.
