Como classificar a ordem dos arquivos SFTP pela última atualização usando java?
Quero ler todos os arquivos já carregados hoje.
e entre isso eu tenho que imprimir as três últimas propriedades do arquivo carregado. (nome, hora do upload, tamanho). Agora poderei imprimir o nome e as propriedades do presente arquivado no servidor FTP, mas ele não está em uma ordem e é exibido como um lixo eletrônico. Agora, quero imprimir o nome, tamanho, caminho, hora de upload dos últimos três arquivos enviados.
Alguém pode me ajudar a conseguir isso?
Aqui está o meu trecho:

Ajuda, por favor, pesquisei bastante no Google, mas não consigo acessar a classificação de arquivos FTP.
Qualquer ajuda será muito apreciada.
