How to convert OffsetDateTime to Epoch Seconds in Java

In Java, with a given OffsetDateTime object we can use the to the toEpochSecond() method to convert it to a number of seconds from the epoch of 1970-01-01T00:00:00Z as the following Java code.

ConvertOffsetDateTimeToEpochSecondsExample1.java 

import java.time.OffsetDateTime;

public class ConvertOffsetDateTimeToEpochSecondsExample1 {
    public static void main(String... args) {
        OffsetDateTime offsetDateTime = OffsetDateTime.parse("2022-05-08T14:10:20.878564600+02:00");

        long epochSeconds = offsetDateTime.toEpochSecond();

        System.out.println("OffsetDateTime: " + offsetDateTime);
        System.out.println("Epoch Seconds: " + epochSeconds);
    }
}
The output as below. 
OffsetDateTime: 2022-05-08T14:10:20.878564600+02:00
Epoch Seconds: 1652011820
