chat program in java using socket

Java implements Simple Chat Room instances based on socket This example describes how to implement a simple chat room in Java based on socket. Share it with you for your reference. The specific implementation method is as follows:

(online) {InputStream in; Try{ in=Socket.getinputstream (); BufferedReader BR=NewBufferedReader (NewInputStreamReader (in)); String Back=Br.readline (); System.out.println (back); } Catch(IOException e) {e.printstacktrace (); } } } } Public Static voidMain (string[] args) {Try{Client C=NewClient (); System.out.println ("Started!"); } Catch(unknownhostexception e) {e.printstacktrace (); } Catch(IOException e) {e.printstacktrace (); } }}View CodeR

Simple interface: Train of thought: 1. First create the interface in the previous illustration 2. Add related event listener Events 3. Use multithreading to design the sender and receiver 4. Create thread initiation threads in the Send button and the receiving end respectively. 5.

Socket is the most basic communication interface in network programming, commonly used network auxiliary class, such as URL and so on, its bottom or based on socket to achieve. and socket, image, is the connection between the two ends of communication, such as S The concrete effect looks the following picture: This is only in the local trial effect, if you a

Originally this homework I want to make a graphical interface, but the reality is that I understand test instructions wrong, and then lost the initial interest, or the program into a function of the correct but "UI" unfriendly console, but no matter how, the development of the pre-graphic interface is very rewarding, after all, to tell the truth, It is not easy to make a tangible color of Java, and with the

I need to learn about socket recently, so I just ran a chat demo. Basically, I copied someone else. I added an util class and optimized it. If you have a swing interface, students and beginners can take it away. Http://download.csdn.net/detail/sysmaid/3880649 Paste some code.
