# Duration toHours() method in Java

Java 8ProgrammingObject Oriented Programming

The value of a duration in the form of a number of hours can be obtained using the method toHours() in the Duration class in Java. This method does not require any parameters and it returns the duration in the form of a number of hours.

A program that demonstrates this is given as follows −

## Example

Live Demo

import java.time.Duration;
public class GFG {
public static void main(String[] args) {
Duration d = Duration.ofDays(1);
System.out.println("The duration is: " + d);
System.out.println("Number of hours in the duration is: " + d.toHours());
}
}

## Output

The duration is: PT24H
Number of hours in the duration is: 24

Now let us understand the above program.

The duration is displayed and then the number of hours in it is displayed using the toHours() method. A code snippet that demonstrates this is as follows −

Duration d = Duration.ofDays(1);
System.out.println("The duration is: " + d);
System.out.println("Number of hours in the duration is: " + d.toHours());
