Client Side Socket

Using Socket is pretty simple, first creates a new instance passing it the host name and the port number. Then create the concret stream classes for the input and the output stream.

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.IOException;
import java.net.Socket;
