A file transfer application built using Java Socket Programming. It allows the client to download and upload files to a server using a GUI built with Java AWT and SWING.

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 😉
