Read File Description

In documentation, there is written like,

// Create the file transfer manager
FileTransferManager manager = new FileTransferManager(connection);
// Create the outgoing file transfer
OutgoingFileTransfer transfer = manager.createOutgoingFileTransfer("romeo@montague.net");
// Send the file
transfer.sendFile(new File("shakespeare_complete_works.txt"), "You won't believe this!");

now i want to read this description which is "You won't believe this!" in IncomingFileTransfer.

How can i get it????
