LocalDateTime getHour() method in Java with Examples

The getHour() method of an LocalDateTime class is used to return the hour-of-day field. This method returns an integer value ranging from 0 to 23, i.e. the Hours of a day.

Syntax:

public int getHour()

Parameter: This method does not accept any parameter.

Returns: This method returns an integer value which represents the hour-of-day and it ranges from 0 to 23.

Below programs illustrate the LocalDateTime.getHour() method:

Program 1:

// Java program to demonstrate
// LocalDateTime.getHour() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a LocalDateTime Object
        LocalDateTime local
            = LocalDateTime.parse("2018-12-03T12:39:10");

        // get HourOfDay
        int hourOfDay = local.getHour();

        // print result
        System.out.println("HourOfDay: "
                           + hourOfDay);
    }
}

Output:

HourOfDay: 12

Program 2:

// Java program to demonstrate
// LocalDateTime.getHour() method

import java.time.*;

public class GFG {
    public static void main(String[] args)
    {

        // create a LocalDateTime Object
        LocalDateTime local
            = LocalDateTime.parse("2019-01-28T22:29:10");

        // get HourOfDay
        int hourOfDay = local.getHour();

        // print result
        System.out.println("HourOfDay: "
                           + hourOfDay);
    }
}

Output:

HourOfDay: 22
