DurationDemo.java

import java.time.Duration;
import java.time.LocalDateTime;
import java.time.temporal.Temporal;

public class DurationDemo
{
    public static void main(String[] args)
    {
        Duration duration = Duration.ofDays(5);
        System.out.println("duration = "+duration);

        LocalDateTime localDateTime = LocalDateTime.now();
        System.out.println("localDateTime = "+localDateTime);

        /*
         * Parameters:
         *
         * temporal - the temporal object to adjust, not null
         *
         * Returns:
         *
         * an object of the same type with the adjustment made, not
         * null
         */
        Temporal temporal = duration.subtractFrom(localDateTime);
        System.out.println("temporal = "+temporal);

    }

}

Output

duration = PT120H
localDateTime = 2018-03-23T09:10:38.480
temporal = 2018-03-18T09:10:38.480
