HI,
 I want to write a simple server/client chat program. But i get an
error message:

"server.java:49: non-static method accept() cannot be referenced from a
static context
         Socket clientSocket = ServerSocket.accept();"
                                           ^

I dont know much of a static, non-static methods yet, so I ask:  Could
some one fix this problem for me?

The code provided is not fully done yet, and after it is fixed more
errors can appiear too :-). All suggestions are wellcome.

The code:
