Java Convert LocalTime to Seconds of Day

Tags: Java LocalTime Java 8

In this Java core tutorial we learn how to convert a java.time.LocalTime object into a number of seconds of day in Java programming language.

How to convert LocalTime to Seconds of Day

With a given LocalTime object we can use the toSecondOfDay() method to extract the time as seconds of day. In the following Java program we learn how to use the LocalTime.toSecondOfDay() method .

ConvertLocalTimeToSecondOfDayExample1.java 

import java.time.LocalTime;

public class ConvertLocalTimeToSecondOfDayExample1 {
    public static void main(String... args) {
        int hour = 10;
        int minute = 20;
        int second = 30;

        LocalTime localTime = LocalTime.of(hour, minute, second);
        int secondOfDay = localTime.toSecondOfDay();

        System.out.println("LocalTime: " + localTime);
        System.out.println("Second of Day: " + secondOfDay);
    }
}
The output as below. 
LocalTime: 10:20:30
Second of Day: 37230
