IntelliJ IDEA, missing file in the JAR

Display - Best Practice (hopefully)

Mon, 01 Jun 2009 17:02:36 GMT

For some time I was happy with the way I've written the code to handle showing information on device display. This topic was not discussed at my university, I guess no one actually does it, we were just provided with sample application that did whatever task been showcased during the lecture. Same applies to books that I've read so far, in regards to mobile development ( Beginning J2ME: From Novice to Professional, Kicking Butt with MIDP and MSA - Creating Great Mobile Applications, Enterprise J2ME Wireless Applications and J2ME in a Nutshell), not one of them actually explained how display changing action should be performed. After recently starting to study for my SCJP exam (SCJP Sun Certified Programmer) I asked my self "Do I really do it the best way?".
