Two Way Chat

In two way chat we have two programs one is a server and the other is a client

Here in server program we create a server socket with a port of 6789(can be changed) by usingser=new ServerSocket(6789); and socket is connected to it by using socket=ser.accept(); Also we create inputstream reader and outputstream reader in the server.java file

In client we create a socket and connect it to the port number 6789 by using  socket=new Socket(InetAddress.getLocalHost(),6789); Also we create inputstream reader and outputstream reader in the client.java file

 For running the Chat we have to run server using a one command prompt and client using another command prompt.
