Good morning, someone can help me? I have a Java application and I need to do a conversion .. In which is the localDate for unixtime .. How can I do this?
This is my localDate:
for (Telemetry telemetry : listTelemetry) {
telemetry.getInstant();
}
Entity:
public LocalDateTime getInstant() {
return instant;
}
You can use it as well
public Long getInstant() {
Date date = new Date();
return date.getTime();
}
Consider the type of the returned data that in the case of getTime is a Long representing a TimeStamp.
Date will return an object containing the System Current Date and Time as defined by the Operating System.
To use the LocalDateTime object you can use this:
LocalDateTime d = LocalDateTime.now(); // momento atual
// Use ZoneId.systemDefault() para pegar o ZoneId do SO
Date date2 = Date.from(d.atZone(ZoneId.systemDefault()).toInstant());
// ou defina qual ZoneId deseja
Date date2 = Date.from(d.atZone(ZoneId.of("America/Sao_Paulo")).toInstant());
System.out.println(date2.getTime());
If you want to return the LocalDateTime object from a Database information use something like this
String str = "1986-04-08 12:30";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm");
LocalDateTime dateTime2 = LocalDateTime.parse(str, formatter);
Date date3 = Date.from(dateTime2.atZone(ZoneId.of("Europe/London")).toInstant());
System.out.println(date3.getTime());
