The FTPClient is used for plain FTP, the FTPSClient for FTP over SSL, as you could have read in the JavaDoc.

FTPS is an alternate solution comes the FTP over SSL, or FTPS. A set of security extensions were added to the old FTP so that it allows encryption on both command and data connections. That is actually greater than it sounds, since SSL connection is time-consuming and it can be a heavy job to negotiate it twice. The certificate is installed on the server, so all you need to do is configure your preferred client.
