start Server first
start Client by passing the ipaddress of the server
eg; java Client 10.0.1.15
if an error pops up change the port in both Client and Server programs

what ip ??????its sever running ip?
set ip to:
InetAddress host = InetAddress.getLocalHost();
String diffHost = "10.215.177.201";
Socket sock = new Socket(diffHost,PORT);
System.out.println("Chat Client Started");
& run client fallowing exception throw>>>>>>
run:
Chat Client Started
