# TCP-File-Transfer

This is a Java application that :

- uses TCP for file transfer.
	
- has a user interface buit using Java AWT and Java Swing.
	
- is built using Java Socket Programming.
	
- allows multiple users to connect to a server at once. It accomplishes this through multithreading.
	
- mandates the server to specify working directory as a command line argument with the freedom to specify a custom 	  port number as the second argument. The default port number has been set to 3333.
	
- server assigns connection IDs to the clients connected.
	
- mandates client to specify working directory as a command line argument. It allows user to specify host address and   if not specified, defaults it to Localhost. The user can also specify the port number as the third argument.
	
- Displays files and directories present in the server working directory and allows the client to select files and     download them onto the client system.
	
- Allows the client to upload files to the server working directory. This allows 2 clients to transfer files through   the server.
	
- You may call it ShareIt, Xender or something similar for laptops and PCs :wink:
