In this guide, you will learn about the LocalTime getHour() method in Java programming and how to use it with an example.

1. LocalTime getHour() Method Overview

Definition:

The getHour() method of the LocalTime class in Java is used to get the hour-of-day field from the LocalTime instance, which ranges from 0 to 23 representing the hour of the day in 24-hour clock format.

Syntax:

public int getHour()

Parameters:

The method does not take any parameters.

Key Points:

- The getHour() method returns the hour part of the LocalTime object.

- The returned value ranges from 0 (midnight) to 23 (11 PM) representing hours in a day.

- This method does not modify the original LocalTime object, as LocalTime instances are immutable.

2. LocalTime getHour() Method Example

import java.time.LocalTime;

public class LocalTimeGetHourExample {
    public static void main(String[] args) {
        // Create a LocalTime object representing 15:45 (3:45 PM)
        LocalTime time = LocalTime.of(15, 45);
        System.out.println("Local Time: " + time);

        // Retrieve the hour of the day using getHour() method
        int hour = time.getHour();
        System.out.println("Hour of the Day: " + hour);
    }
}

Output:

Local Time: 15:45
Hour of the Day: 15

Explanation:

In this example, a LocalTime object representing 3:45 PM (15:45 in 24-hour clock format) is created. The getHour() method is then called on this object to retrieve the hour of the day, which is 15 in this case. The obtained hour value is printed to the console, demonstrating the usage of the getHour() method.
