We will look at four network applications, written completely from scratch in Java. Each of these applications use the client-server paradigm, which we discussed earlier. Java sockets have input streams and output streams built in, which makes programming rather pleasant. Four applications are presented in order of increasing complexity: A trivial date server and client , illustrating simple one-way communication. The server sends data to the client only. A capitalize server and client , illustrating two-way communication , and server-side threads to more efficiently handle multiple connections simultaneously.

A two-player tic tac toe game , illustrating a server that needs to keep track of the state of a game , and inform each client of it, so they can each update their own displays. A multi-user chat application , in which a server must broadcast messages to all of its clients. These applications communicate insecurely. None of these applications even try to secure communication.

Java is a general-purpose programming language that is class-based , object-oriented , and designed to have as few implementation dependencies as possible. It is intended to let application developers write once, run anywhere WORA , [17] meaning that compiled Java code can run on all platforms that support Java without the need for recompilation.

As of [update] , Java was one of the most popular programming languages in use according to GitHub , [19] [20] particularly for client-server web applications , with a reported 9 million developers. Java was originally developed by James Gosling at Sun Microsystems which has since been acquired by Oracle and released in as a core component of Sun Microsystems’ Java platform.

The original and reference implementation Java compilers , virtual machines, and class libraries were originally released by Sun under proprietary licenses. Oracle and others highly recommend uninstalling older versions of Java because of serious risks due to unresolved security issues.
