Below examples illustrate the Duration.of() method: Example 1:Â
Java
// Java code to illustrate duration of() methodÂ
import java.time.*;import java.time.temporal.*;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // input amount of time        long timeAmount = 5;Â
        // Duration using of() method        Duration duration            = Duration.of(timeAmount, ChronoUnit.DAYS);Â
        System.out.println(duration.getSeconds());    }} |
Output:
432000
Example 2:Â
Java
// Java code to illustrate duration of() methodÂ
import java.time.*;import java.time.temporal.*;Â
public class GFG {Â Â Â Â public static void main(String[] args)Â Â Â Â {Â
        // input amount of time        long timeAmount = 5;Â
        // Duration using of() method        Duration duration            = Duration.of(timeAmount, ChronoUnit.HOURS);Â
