DurationDemo1.java

import java.time.Duration;

public class DurationDemo1
{
    public static void main(String[] args)
    {
        /*
         * Parameters:
         *
         * nanos - the number of nanoseconds, positive or negative
         *
         * Returns:
         *
         * a Duration, not null
         */

        Duration duration1 = Duration.ofNanos(2000000);
        System.out.println("duration1 = "+duration1);
       
        /*
         * Parameters:
         *
         * seconds - the number of seconds, positive or negative
         *
         * Returns:
         *
         * a Duration, not null
         */

        Duration duration2 = Duration.ofSeconds(10);
        System.out.println("duration2 = "+duration2);
    }

}

Output

duration1 = PT0.002S
duration2 = PT10S

DurationDemo2.java

import java.time.Duration;
import java.time.temporal.ChronoUnit;

public class DurationDemo2
{
    public static void main(String[] args)
    {
        /*
         * Parameters:
         *
         * seconds - the number of seconds, positive or negative
         *
         * nanoAdjustment - the nanosecond adjustment to the number of
         * seconds, positive or negative
         *
         * Returns:
         *
         * a Duration, not null
         */

        Duration duration1 = Duration.ofSeconds(10, 909090);
        System.out.println("duration1 = " + duration1);

        /*
         * Parameters:
         *
         * amount - the amount of the duration, measured in terms of
         * the unit, positive or negative
         *
         * unit - the unit that the duration is measured in, must have
         * an exact duration, not null
         *
         * Returns:
         *
         * a Duration, not null
         */

        Duration duration2 = Duration.of(10, ChronoUnit.DAYS);
        System.out.println("duration2 = " + duration2);
    }

}

Output

duration1 = PT10.00090909S
duration2 = PT240H
