PART 4
Communicating with
the Rest of the World
Support for networked communications has been a crucial component of Java since the
beginning, and Java ME continues this trend, bringing with it essential contributions to the
entire community of Java developers. The three chapters in this part look at the key
aspects of creating Java ME applications that use the Internet. In Chapter 12, you'll learn
how to use the GCF, one of the most important frameworks and APIs provided by Java ME.
It pervades Java ME's notions of how applications communicate across physical inter-
faces such as networks. In Chapter 13, you'll learn what options you have when working
with XML—an important facet of many communicating applications today. Finally, in
Chapter 14, you'll see how to access the wide-area wireless networking capabilities found
on many Java ME devices.
