Java - como formatar a data atual com o padrão de milissegundos, por exemplo: yyyy-MM-dd HH: mm: ss.milliseconds
3 points
Em java, podemos exibir a hora atual com o padrão de milissegundos quando usamos o padrão SSS .
Ex.:
xxxxxxxxxx1
yyyy-MM-dd HH:mm:ss.SSSxxxxxxxxxx1
import java.time.LocalDateTime;2
import java.time.format.DateTimeFormatter;3

public class Example1 {5
6
public static void main(String[] args) {7
8
DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS");9
LocalDateTime localDateTime = LocalDateTime.now();10
11
String format = fmt.format(localDateTime);12
System.out.println(format); // 2019-10-13 12:56:53.22013
}14
}Resultado:
xxxxxxxxxx1
2019-10-13 12:56:53.220xxxxxxxxxx1
import java.time.ZonedDateTime;2
import java.time.format.DateTimeFormatter;3

public class Example2 {5

public static void main(String[] args) {7
8
DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS Z");9
ZonedDateTime zonedDateTime = ZonedDateTime.now();10
11
String format = fmt.format(zonedDateTime);12
System.out.println(format); // 2019-10-13 13:07:10.912 +020013
}14
}Resultado:
xxxxxxxxxx1
2019-10-13 13:07:10.912 +0200xxxxxxxxxx1
