Oi Atualmente, estou tentando importar o arquivo CSV para o Java para plotar os dados. Basicamente, posso importar com êxito, mas ele não funciona no meu CSV porque tem o formato de hora como:HH:mm:ss MM-dd-yy

Os dados são os seguintes:

2016-05-15 00:00:00 0
2016-05-15 00:00:00 0
2016-05-15 00:00:00 5.44852
2016-05-15 00:00:01 0
2016-05-15 00:00:01 0
2016-05-15 00:00:01 5.26064

o código é o seguinte:

}

mas não sei como colocar o formato da hora nesse código. Obrigado por quem puder me ajudar com isso.
