In this article, we will discuss different ways to compare two instances of ZonedDateTime in Java 1.8 version
1. Comparing two ZonedDateTime instances :
There are different methods available to compare two ZonedDateTime instances, those are –
- compareTo(ChronoZonedDateTime) –
- This method compares invoking ZonedDateTime with another ZonedDateTime
- isBefore(ChronoZonedDateTime) –
- This method checks if invoking ZonedDateTime is before the specified ZonedDateTime
- isAfter(ChronoZonedDateTime) –
- This method checks if invoking ZonedDateTime is after the specified ZonedDateTime
- isEqual(ChronoZonedDateTime) –
- This method checks if invoking ZonedDateTime is equal to the specified ZonedDateTime
- equals(Object) –
- This method checks if invoking ZonedDateTime is equal to another ZonedDateTime
2. Examples for Comparing two ZonedDateTime :
- Using compareTo(ChronoZonedDateTime) method
- Using isBefore(ChronoZonedDateTime) method
- Using isAfter(ChronoZonedDateTime) method
- Using isEqual(ChronoZonedDateTime) method
- Using equals(Object) method
2.1 Using compareTo(ChronoZonedDateTime) method :
- This method compares invoking ZonedDateTime with another ZonedDateTime and returns integer value based on the comparison
- Returns Zero, if both ZonedDateTime in comparison are equal
- Returns Positive value, if invoking ZonedDateTime is latter-than (greater-than) the specified ZonedDateTime
- Returns Negative value, if invoking ZonedDateTime is earlier-than (lesser-than) the specified ZonedDateTime

public static void main(String[] args) {
// 1. get Current Zoned Date/time
ZoneId zoneIdLocal = ZoneId.systemDefault();
ZonedDateTime currentZonedDateTime = ZonedDateTime.of(2022, 8, 15, 12, 30, 30, 500, zoneIdLocal);
System.out.println("1. Current Zoned Date/time is = " + currentZonedDateTime);
// 2. form Past Date/time
ZoneId zoneIdPast = ZoneId.of("Australia/Sydney");
ZonedDateTime pastZonedDateTime = ZonedDateTime.of(2022, 8, 15, 12, 30, 30, 500, zoneIdPast);

// 3. form Future Date/time
ZoneId zoneIdFuture = ZoneId.of("America/Chicago");
ZonedDateTime futureZonedDateTime = ZonedDateTime.of(2022, 8, 15, 12, 30, 30, 500, zoneIdFuture);
