The getEpochSecond() method of Instant class is used to return the number of seconds from the Java epoch of 1970-01-01T00:00:00Z. It means the difference between time in seconds of this instance and time represented by ā1970-01-01T00:00:00Zā is returned by this method. The epoch second count is a simple incrementing count of seconds where the second 0 is 1970-01-01T00:00:00Z.
Syntax:
public long getEpochSecond()
Returns: This method returns the seconds from the epoch of 1970-01-01T00:00:00Z.
Below programs illustrate the Instant.getEpochSecond() method:
Program 1:
// Java program to demonstrate// Instant.getEpochSecond() methodĀ Ā import java.time.*;Ā Ā public class GFG {Ā Ā Ā Ā public static void main(String[] args)Ā Ā Ā Ā {Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā // createĀ instance objectĀ Ā Ā Ā Ā Ā Ā Ā Instant instantĀ Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā = Instant.parse("2018-10-20T16:55:30.00Z");Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā // print Instant ValueĀ Ā Ā Ā Ā Ā Ā Ā System.out.println("Instant: " + instant);Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā // get epochValue using getEpochSecondĀ Ā Ā Ā Ā Ā Ā Ā long epochValue = instant.getEpochSecond();Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā // print resultsĀ Ā Ā Ā Ā Ā Ā Ā System.out.println("Java epoch Value: "Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā + epochValue);Ā Ā Ā Ā }} |
Output:
Instant: 2018-10-20T16:55:30Z Java epoch Value: 1540054530
Program 2:
