Title:The Design and Implementation
for LAN Online Communication
Abstract
With the gradual development of the Internet,the Internet has become the primary method that people get the message.Some traditional information exchange as e-mail,because it has a reason for the delay in the delivery of the message failed to meet our requirements to obtain real-time information.IM came into being, to provide the public a new integrated information exchange platform.LAN chat room is a chat mode that a lot of people used.We can use a variety of programming languages to complete this feature-rich LAN chat rooms.
This paper designed and implemented a LAN chat room,the system uses the client and server-side architecture,using a graphical java components developed simple and elegant and rational structure of the client and server interfaces.It uses Socket network programming technology interact client and server side of the connection,the data input and output streams through rational design,implementation,communication and display of information. Meanwhile,the system achieved a single user chat,group chat,file transfer,and administrator functions.
