It has been nearly a decade since I started Java ME(J2ME) programming. It was a very exciting experience being the first author on this subject in India and being one of the first trainers on this subject in the whole of South Asia. After training top corporates like Reliance Communications, LG, Kyocera, Mahindra Satyam etc for big bucks now I have shared my book for free for the benefit of all Java ME (J2ME) programmers. I hope it will benefit all the readers. This book contains my experience of designing mobile games and applications.
