Write a client to server program using TCP. Client sends request to server and server sends reply back. 

Client can send the following request to server:

 1. Add user first names, last names and a random 3-digit ID to database.

2. Option to add/remove users

3. Display all users 

I can write the program in java. However, I just dont know how to write a client to server program. How would I start this?
