MMulti threaded Socket Server-Client Chat Program - Hello World
|
Hi,
You will find three classes, Server.java, Client.java and CreateThread.java
first run the server and then client, you can open many clients, the server code will support. This example is just a hello world type, so dont expect more. It will just teach you on how to create multithreaded socket. Happy learning.. Write to me for more JAVA...........:). I proclaim that this code is fully mine, since being a corporate trainer, I make Technology easy with these simple examples. Keep looking for more ....

try{
ss=new ServerSocket(2000);
System.out.println("Server Ready");
while(true){
s=ss.accept();
CreateThread.getInstance().spanThread(s);
}
}catch(Exception
e){System.out.println(e);}
