Method:

public long until(Temporal endExclusive,

                  TemporalUnit unit)

This method calculates the amount in provided unit between this date-time and the provided temporal.

In other words, this method returns the amount of time between two LocalDateTime objects in terms of a single TemporalUnit



Examples


package com.logicbig.example.localdatetime;

import java.time.LocalDateTime;
import java.time.temporal.ChronoUnit;

public class UntilExample {

    public static void main (String... args) {
        LocalDateTime dt = LocalDateTime.of(1999, 1, 20,
                                            20, 10, 30);
        LocalDateTime dt2 = LocalDateTime.of(2005, 10, 1,
                                             10, 5);

        long l = dt.until(dt2, ChronoUnit.DAYS);
        System.out.printf("DAYS between %s and %s => %s%n", dt, dt2, l);

        l = dt.until(dt2, ChronoUnit.HOURS);
        System.out.printf("HOURS between %s and %s => %s%n", dt, dt2, l);

        l = dt.until(dt2, ChronoUnit.MONTHS);
        System.out.printf("MONTHS between %s and %s => %s%n", dt, dt2, l);

        l = dt.until(dt2, ChronoUnit.YEARS);
        System.out.printf("YEARS between %s and %s => %s%n", dt, dt2, l);
    }


}

Output

DAYS between 1999-01-20T20:10:30 and 2005-10-01T10:05 => 2445
HOURS between 1999-01-20T20:10:30 and 2005-10-01T10:05 => 58693
MONTHS between 1999-01-20T20:10:30 and 2005-10-01T10:05 => 80
YEARS between 1999-01-20T20:10:30 and 2005-10-01T10:05 => 6
