JapaneseDate toEpochDay() method in Java with Example

The toEpochDay() method of java.time.chrono.JapaneseDate class is used to get the number of epoch days present in between the current Japanese date and 1970-01-01. Syntax:

public long toEpochDay()

Parameter: This method does not accept any argument as a parameter. Return Value: This method returns the number of epoch days present in between the current Hijrah date and 1389-10-22. Below are the examples to illustrate the toEpochDay() method: Example 1:

Java

// Java program to demonstrate
// toEpochDay() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate = JapaneseDate.now();

            // Getting no of epoch days present
            // by using toEpochDay() method
            long length = hidate.toEpochDay();

            // Display the result
            System.out.println("EpochDay : "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

EpochDay : 18365

Example 2:

Java

// Java program to demonstrate
// toEpochDay() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.temporal.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // Creating and initializing
            // JapaneseDate Object
            JapaneseDate hidate
                = JapaneseDate.of(1970, 01, 01);

            // Getting no of epoch days present
            // by using toEpochDay() method
            long length = hidate.toEpochDay();

            // Display the result
            System.out.println("EpochDay : "
                               + length);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can"
                               + " not form a date");
            System.out.println("Exception thrown: "
                               + e);
        }
    }
}

Output:

EpochDay : 0
