Instead, this book will help you through the myriad details of understanding J2ME architecture and programming J2ME applications.
In this chapter, we will present an overview of J2ME’s primary components, including virtual machines, configurations, and profiles. We’ll then present a few short examples of J2ME-enabled applications to whet your appetite and to show you how easy it is to get started with J2ME.
