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());
    }
}

Output:

50

Example 2:

// 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 = -445000;

        // Duration using ofMillis() method
        Duration duration
            = Duration.ofMillis(noOfMillis);

        System.out.println(duration.getSeconds());
    }
}

Output:

-445
