You can use org.apache.commons.net.ftp.FTPClient

FTPClient f = new FTPClient();
f.connect(server);
f.login(username, password);

FTP is a different protocol from HTTP. There is no "GET" request in FTP. In order to understand how the requests and responses look, read the RFC959 FTP specification.

From a Java perspective, you could try org.apache.commons.net.ftp.FTPClient.
