3a: Write a network server program in Java where the server waits for incoming client connections using stream type sockets. Once a client connects it sends a String object to the server with a simple query - the server then responds with a text based response. The connection is then terminated. The server should use a separate thread of execution for each new client connection and all interaction between the server and the client should be done within this thread. The answer only needs to include source code for the server side application. 12 MARKS
