The ofSeconds(long, long) method of Duration Class in java.time package is used to get a duration in a 1 second format. In this method, the seconds are calculated as total seconds in 1 second format, i.e. 1 second per second. The second parameter nanoAdjustment is used to adjust the seconds in nanoSeconds unit.
Syntax:
public static Duration ofSeconds(long seconds, long nanoAdjustment)
Parameters: This method accepts two parameters:
- seconds: which is the number of seconds. It can be positive or negative.
- nanoAdjustment: which is the adjustment to be made in the seconds.
Return Value: This method returns a Duration representing the time in 1 second format.
Exception: This method throws ArithmeticException if the input seconds exceeds the capacity of Duration.
Below examples illustrate the Duration.ofSeconds() method:
Example 1:
// Java code to illustrate ofSeconds() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // input number of Seconds        long noOfSeconds = 214545;          // input nanoSeconds adjustment to be made        long nanoSecAdjust = 10000;          // Duration using ofSeconds() method        Duration duration            = Duration.ofSeconds(noOfSeconds);        Duration duration1            = Duration.ofSeconds(noOfSeconds,                                 nanoSecAdjust);          System.out.println("Duration without adjustment: "                           + duration.getSeconds());        System.out.println("Duration with adjustment: "                           + duration1.getSeconds());    }} |
Output:
Duration without adjustment: 214545 Duration with adjustment: 214545
Example 2:
// Java code to illustrate ofSeconds() method  import java.time.Duration;  public class GFG {    public static void main(String[] args)    {          // input number of Seconds        long noOfSeconds = 214545;          // input nanoSeconds adjustment to be made        long nanoSecAdjust = -10000;          // Duration using ofSeconds() method        Duration duration            = Duration.ofSeconds(noOfSeconds);        Duration duration1            = Duration.ofSeconds(noOfSeconds,                                 nanoSecAdjust);          System.out.println("Duration without adjustment: "                           + duration.getSeconds());        System.out.println("Duration with adjustment: "                           + duration1.getSeconds());    }} |
Output:
Duration without adjustment: 214545 Duration with adjustment: 214544
