Below examples illustrate the Duration.ofMillis() method:
Example 1:
// Java code to illustrate ofMillis() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // input number of Millis        long noOfMillis = 50000;          // Duration using ofMillis() method        Duration duration            = Duration.ofMillis(noOfMillis);          System.out.println(duration.getSeconds());    }} |
