Java LocalDateTime of() Method
Example
Create a fixed date and time:
import java.time.LocalDateTime;
public class Main {
public static void main(String[] args) {
LocalDateTime myDateTime = LocalDateTime.of(2026, 1, 15, 14, 30);
System.out.println(myDateTime);
}
}Definition and Usage
The of() method creates a LocalDateTime object from a year, a month, a day, an hour and a minute, and optionally a second and a nanosecond (a billionth of a second).
You can also make it from a LocalDate and a LocalTime: LocalDateTime.of(myDate, myTime).
