The getHour() method of a ZonedDateTime class used to get the hour-of-day field from this ZonedDateTime. This method returns the integer value for the hour from 0 to 23.
Syntax:
public int getHour()
Parameters: This method does not take any parameters.
Return value: This method returns an integer representing hour, from 0 to 23.
Below programs illustrate the getHour() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.getHour() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");          // get hour field        int value = zoneddatetime.getHour();          // print result        System.out.println("hour: " + value);    }} |
Output:
hour: 19
Program 2:
// Java program to demonstrate// ZonedDateTime.getHour() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-10-25T23:12:38.543+02:00[Europe/Paris]");          // get hour field        int value = zoneddatetime.getHour();          // print result        System.out.println("hour: " + value);    }} |
Output:
hour: 23
