Return value:

The return type of this method is int, it returns the value hour-of-day field of this object and the number of hours in a day starts from 0 and ends at 23.

Example:

// Java program to demonstrate the example 
// of getHour() method of LocalDateTime

import java.time.*;

public class GetHourOfLocalDateTime {
    public static void main(String args[]) {
        // Instantiates two LocalDateTime
        LocalDateTime da_ti1 = LocalDateTime.parse("2005-10-05T10:10:10");
        LocalDateTime da_ti2 = LocalDateTime.now();

        // Display da_ti1, da_ti2
        System.out.println("LocalDateTime da_ti1 and da_ti2: ");
        System.out.println("da_ti1: " + da_ti1);
        System.out.println("da_ti2: " + da_ti2);

        System.out.println();

        // Here, this method returns the
        // field value hour-of-day from 
        // this date-time object (da_ti1)
        int hod = da_ti1.getHour();

        // Display hod
        System.out.println("da_ti1.getHour(): " + hod);

        // Here, this method returns the 
        // field value hour-of-day from 
        // this date-time object (da_ti2)
        hod = da_ti2.getHour();

        // Display hod
        System.out.println("da_ti2.getHour(): " + hod);
    }
}

Output

LocalDateTime da_ti1 and da_ti2: 
da_ti1: 2005-10-05T10:10:10
da_ti2: 2020-06-05T02:54:33.968481

da_ti1.getHour(): 10
da_ti2.getHour(): 2
