How to convert number of days to hours in Java

In Java, with a number of days we can use the java.time.Duration class to convert it to number of hours as the following Java code.

ConvertDaysToHoursExample1.java 

import java.time.Duration;

public class ConvertDaysToHoursExample1 {
    public static void main(String... args) {
        long numberOfDays = 365;

        // Convert number of days to hours
        Duration duration = Duration.ofDays(numberOfDays);
        long numberOfHours = duration.toHours();

        System.out.println("Number of days: " + numberOfDays);
        System.out.println("Number of hours: " + numberOfHours);
    }
}
The output as below.
