Tags: Java Duration Java 8

In this Java core tutorial we learn how to convert a number of milliseconds to java.time.Duration object in Java programming language.

How to convert milliseconds to Duration in Java

In Java, we can use the Duration.ofMillis(long millis) static method to instantiate a Duration object from number of milliseconds as the example Java code below.

ConvertMillisecondsToDurationExample1.java 

import java.time.Duration;

public class ConvertMillisecondsToDurationExample1 {
    public static void main(String... args) {
        long numberOfMilliseconds = 20000;

        // Convert number of milliseconds to Duration
        Duration duration = Duration.ofMillis(numberOfMilliseconds);

        System.out.println("Number of milliseconds: " + numberOfMilliseconds);
        System.out.println("Duration: " + duration);
    }
}
The output as below. 
Number of milliseconds: 20000
Duration: PT20S
