Duration ofSeconds(long, long) method in Java with Examples

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
