DurationDemo.java

import java.time.Duration;
import java.time.LocalTime;

public class DurationDemo
{
    public static void main(String[] args)
    {

        Duration duration = Duration.between(LocalTime.NOON,
                LocalTime.MIDNIGHT);
        System.out.println("duration = "+duration);
        /*
         * Returns:true if this duration has a total length less than
         * zero
         */

        System.out.println("is duration Negative? = "+duration.isNegative());

        /*
         * Returns:true if this duration has a total length equal to
         * zero
         */

        System.out.println("is duration zero? = "+duration.isZero());
    }

}

Output

duration = PT-12H
is duration Negative? = true
is duration zero? = false
