J2ME in Nutshell The first nine chapters of this book describe the J2ME platform, the command-line tools that are provided with Sun's J2ME reference implementations, and some of the visual development environments that you can use when writing J2ME applications:
This chapter introduces the J2ME platform and the concepts of configuration and profile, and it compares J2ME to a number of other Java platforms for small devices.
This chapter covers the Connected Limited Device Configuration (CLDC), which is the basic building block for the J2ME profiles for wireless devices and PDAs. It begins by outlining the differences between CLDC and the core libraries of the J2SE platform. Then it takes a close look at KVM, the small-footprint virtual machine that is used in Sun's reference implementation of CLDC.
