LocalDate Class toEpochDay() method

• toEpochDay() method is available in java.time package.
• toEpochDay() method is used to convert this LocalDate into a number of days from the java epoch standard format.
• toEpochDay() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• toEpochDay() method does not throw an exception at the time of converting this LocalDate into days.

Syntax:

    public long toEpochDay();

Parameter(s):

• None

Return value:

The return type of this method is long, it returns the conversion value into number of epoch day.

Example:

// Java program to demonstrate the example 
// of long toEpochDay() method of LocalDate

import java.time.*;

public class ToEpochDayOfLocalDate {
    public static void main(String args[]) {
        // Instantiates two LocalDate
        LocalDate l_da1 = LocalDate.parse("2007-04-04");
        LocalDate l_da2 = LocalDate.of(2008, Month.FEBRUARY, 06);

        // Display l_da1,l_da2 
        System.out.println("LocalDate l_da1,l_da2 : ");
        System.out.println("l_da1: " + l_da1);
        System.out.println("l_da2: " + l_da2);

        System.out.println();

        // Here, this method converts this
        // date l_da1 to an epoch day
        long to_epoc_day = l_da1.toEpochDay();

        // Display to_epoc_day
        System.out.println("l_da1.toEpochDay(): " + to_epoc_day);

        // Here, this method converts this
        // date l_da2 to an epoch day
        to_epoc_day = l_da2.toEpochDay();

        // Display to_epoc_day
        System.out.println("l_da2.toEpochDay(): " + to_epoc_day);
    }
}

Output

LocalDate l_da1,l_da2 : 
l_da1: 2007-04-04
l_da2: 2008-02-06

l_da1.toEpochDay(): 13607
l_da2.toEpochDay(): 13915
