Summary
Computers have developed rapidly from their appearance to the present. Computers at this stage are no longer just independent individuals for computing. Along with the development of computers, there is also Internet technology. After a long period of development, Internet technology has changed with each passing day. The development of computer technology is as terrifying as the speed of computer development. From its appearance until now, it has played its own role in all aspects of people's lives, and it is an irreplaceable role. Because the computer has become a cheap commodity, it can be predicted that people will use computers in the future, and the number of people surfing the Internet will gradually increase. People will continue to improve and update better and better Internet services to improve own standard of living. In recent years, my country's economy and society have been developing continuously, and the Internet has also received broad support, and the Internet has been integrated into the daily lives of the majority of people. In terms of computer programming, Internet software development has gradually turned to object-oriented programming technology led by java. Traditional process-oriented programming technology has gradually withdrawn from the stage of history, and java is developing at an incredible speed. Object-oriented technology is used in people's daily life, education, online banking, online shopping, face-to-face online video, and online games that are gradually accepted by the public. Moreover, the advantages and characteristics of java can really reduce the development cost of enterprises and the development time and difficulty of developers.
In the past, people obtained information in a single way, through television, radio, letters and people's word of mouth. This method is very inefficient and the information obtained is also very limited. Searching online has become the main way for people to obtain information at this stage, and it has the characteristics of fast, convenient, and delivery. So people have a need for instant face-to-face chat online. A fresh, simple, and efficient web chat room will definitely be loved by the public. For this purpose, build this chat system.
This article will introduce the design and completion of the Internet chat room program.

Abstract
With the development of Internet technology, network technology is developing very fast in the area of computer technology, one of emerged from it until now, it in many aspects, such as politics, economy, life play an irreplaceable role. With the growing popularity of the computer and popularization, the future will be more and more people use the Internet, enjoy the constantly update and improve the network services, to improve the level of their work lives. With the development of our economy and the popularization of the Internet, the Internet technology is also used more in the daily life of people. In application development and process oriented programming technology is gradually replaced by object-oriented programming technology, the computer software design and development has become the dominant, especially in the development of network technology, the object-oriented Java language programming is development rapidly in explosive. Remote education, online banking, shopping online, video online, and online games are all using object-oriented Java technology. And Java portable features enable Java programs to be compiled into bytecode that is not relevant to the platform, which enables Java programs to run on machines with Java interpreters. It really reduces the development cost of the enterprise and the development time and difficulty of the developer.
In today's society, people's lives have long been inseparable from the Internet. In the future, the life and work of society will depend more on the development of digital technology, more and more networked, digital, electronic and virtualized. E-commerce is also becoming more and more relevant with the development of the Internet and people's life. The use of the development of the Internet and the current situation and development trend, can believe network technology step by step change our work and lifestyle, and social values will all change of step by step.
In today's rapid development of network, the query on the Internet become people to quickly get published, and transfer information important channel, it in many aspects, such as people, political economy, life play an important role. Traditional letter-writing methods do not satisfy people's immediate demand for information. Thus, can chat face to face on the Internet become important human needs, a popular chat tools should be: interface and pure and fresh, simple operation, humanity, saving system resources. For this purpose, build the chat system.
This paper completes the development of an online chat room program through Java's sockets. This article introduces the design and completion of network chat room program.
Key words: chat rooms; the Java; Client / Server;the Socket;
With the development of society and the development of Internet technology, ordinary people can also have their own computers, and they cannot do without the support of network technology in their daily lives. Online instant chat, which replaces telephone calls and letters, has become a popular choice for people. very common way of communication.
This software is made by using the java language developed by sun company, and it is an online chat room based on the C/S model. This system is divided into two parts, server and client. The job of the server is mainly to monitor and receive requests from the client, then process the messages sent by the client, and notify the client. The function of the client is to allow new users to register, log in and use the system through the username and password. Through the cooperative work of the server and the client, the user can finally use the network chat room to complete the communication between users in the chat room.
Development Technology
The system is developed using java technology, and the integrated development environment uses eclipse. Developers should have java programming language, Socket technology, Swing technology, data flow and object-oriented data applications.
Introduction to Internet chat rooms
In today's society, the frequency of use of software that can realize instant messaging is very scary. As a kind of it, the number of users of Internet chat rooms is quite considerable. QQ, which is monopolized in China, and Microsoft's MSN, the industry's big brother, are the focus of public attention and use. Ordinary people can also own their own computers. They cannot do without the support of network technology in their daily lives. It is people's Life has become very convenient and efficient, and you can find the information you want and friends with common interests online. Moreover, many softwares now have a series of functions such as multi-person chat and electronic conference.
Current Situation and Development of Internet Chat Room
Online instant chat room is a widely used technology, and its simple and convenient communication method can be used by a large number of online users. In today's society, online chatting is an important part of Internet services. About 43% of users will use online chatting, ranking fourth. But many people think that chat room is just a way to entertain and pass the time, but lacks the actual value. For now, there are actually not many online chat rooms that can generate income. How it should realize its commercial value has not paid much attention to the outside world.
Now, many companies will develop their own chat rooms, and users log in to the company's server through the user name and password registered on the website. In the chat room, users can express their ideas by inputting text and various symbols to communicate with each other. At present, the technical threshold for developing an online chat room for users is not very high, nor does it require a large amount of funds, and the country has not too restrictive regulations and policies in this regard, so the competition in chat rooms in today's society is actually very high. Fierce, Tencent, Netease, and Sina all have their own online chat rooms, but the concentration of users is not very good. The online chat rooms of each large website will have their own loyal users, and there is no obvious difference between them. Each has its own advantages.
According to the current Internet development report in China released by a certain organization, there are several main reasons why online chat rooms are not favored in business. Independent, not very rich financially. Two: The paid content of most online chat rooms is actually not much, and it is not mandatory.
At present, many websites target the white-collar workers who have already participated in the work with higher income, but do not pay too much attention to the young people who are still in school and entering the society. However, as far as the current social development is concerned, the consumption power of teenagers is actually very considerable. They don’t want to be as economically rigid as the original society, but today’s parents will try their best to meet the needs of their children, whether it is economically or economically. other aspects. Therefore, it is actually very necessary to specifically add some paid content that young people are interested in in the online chat room, which can bring unimaginable benefits. Now many merchants don't know much about the new advertising form. Traditional advertising has affected their thinking in the Internet field. Another aspect is that the advertising model of the online chat room itself is inappropriate. Judging from the current situation, online chat rooms also need to undergo changes, not just to provide instant chat services, but to develop more diversified and professionalized ones. On the one hand, we will continue to develop our own advantages and make instant chat more convenient and fast, which can meet users of different ages, occupations and needs. On the other hand, it can provide users with some other services that are different from chatting, such as the online classroom that has become very popular in recent years, allowing users to learn different professional knowledge without leaving home. It is also acceptable to users. From these aspects, the commercial strength of online chat rooms is very terrifying.
Design of Network Chat Room System
Project Overview
My own chat room is still very simple at present, and it is quite different from those mature online chat rooms on the market, but the basic chat function can also be used, the whole interface is simple, and it is very easy to use convenient.
Design of Network Chat Room System
Server interface:
Login and Registration Interface
User chat interface:
System detailed design
Server Module Design
The main functions of the server are as follows:
One: Ability to turn the server on and off.
Two: Waiting for the request sent by the client from a special port.
Three: The listening port is not fixed, and the server port can be customized.
Four: Ability to broadcast messages to all users connected to the server.
The client and the server are connected through the socket socket, and the use of the socket in java is not complicated, it is very simple. The API provides a special class to deal with, which makes writing programs very simple. The multi-threading technology has been fully embodied on the server side, and the server can handle requests from clients with different IPs at the same time. Monitor whether there is a request from the client by cyclically calling the method of the serversocket object.
Client module design
The main functions of the client are as follows:
One: Able to connect with the server.
Two: New users can register an account.
Three: complete the user's login through the user name and password, and connect to the chat room.
Four: Users can send messages in the chat room.
The client establishes a connection with the server through the socket. The information is transmitted through the flow of java objects, and the server accepts the request and returns the object, and then returns the information to the client. Information from different clients can be processed differently on the server.
