Error in Hashtable put method-Can not resolve symbol

Question

Hi there!I am new to using java.util.Hashtable.
I am using it for a command line instant messaging program for holding the list of clients and list of client names currently connected to the server.
However when I compile my server with the command javac server.java it seems to give errors can not resolve symbol method put (java.lang.object,int).
Here is my code for my server:

Excuse me for not putting my code between tags. I am just sleepless.
I am sending it again.
