1. New instance of application tries to connect to a specific ServerSocket (localhost, port#) to detect running applications. And a running application must have a ServerThread to detect possible run of new instance of the same application
2. The main Logic in steps
• Find existing server socket running on localhost

•  start a new Server thread to detect run of future applications
•  and start the application
