How to convert number of seconds to milliseconds in Java

In Java, with a given number of seconds we can use the Duration.toMillis() method to convert it to milliseconds value as the following Java program.

ConvertSecondsToMillisecondsExample.java 

import java.time.Duration;

public class ConvertSecondsToMillisecondsExample {
    public static void main(String... args) {
        long numberOfSeconds = 10;

        // Convert Number of Seconds to Milliseconds
        long numberOfMilliseconds = Duration.ofSeconds(numberOfSeconds).toMillis();

        System.out.println("Number of seconds: " + numberOfSeconds);
        System.out.println("Number of milliseconds: " + numberOfMilliseconds);
    }
}
The output as below. 
Number of seconds: 10
Number of milliseconds: 10000
