Java is an object-oriented programming language developed by Sun Microsystems. A useful feature of Java is that its programs can be executed on World Wide Web pages. Java programs enable Web pages t i become more interactive with users. The Java language consists of classes and methods that provide basic variable types, system input and output capabilities, and other functions. It also includes classes to support networking, Internet protocols, and graphical user interface functions. Java's networking capabilities are contained in the java.net package. Stream sockets and datagram sockets are provided by Java. With stream sockets a process creates a connection to another process. When the connection is established, data flows between the processes in the stream. JWBCB (Java Whiteboard and ChatBoard) is the network application, using the client/server model, developed for this thesis. Its implementation deepened the author's understanding of basic Java networking capabilities and client/server networking concepts.
