This very quick tour of Sockets programming in Java provided only a sampling of the available methods and classes that can simplify the development of networking applications. Java continues to be developed, and third-party classes provide even more networking functionality. This chapter sampled Java applications that are run standalone, but other techniques exist within Java, such as Applets and Servlets, which provide powerful abstractions for the development of both client and server applications. Although Java is interpreted, it is interpreted at a bytecode level (architecture independent instructions that execute within a virtual machine), and is, therefore, more efficient than most interpreted scripting languages. Java continues to be an important tool and is worth the effort to understand and apply when the opportunity arises.
