In this article, we will learn how to check whether one OffsetDateTime is After another OffsetDateTime using OffsetDateTime.isAfter() method provided in Java 1.8 version
Compare two OffsetDateTime using isAfter() method :
- If there are two OffsetDateTime and the requirement is to check whether one OffsetDateTime is after another OffsetDateTime, then isAfter() method can be used
- isAfter((OffsetDateTime) – checks if the invoking OffsetDateTime is after the specified OffsetDateTime
- Comparison results –
- Returns true, if invoking OffsetDateTime is after the specified OffsetDateTime
- Returns false, if invoking OffsetDateTime is not after the specified OffsetDateTime
- Always returns false for self comparing OffsetDateTime
- Lets see an example for comparing two OffsetDateTime using isAfter() method
CheckOffsetDateTimeIsAfterAnotherOffsetDateTime.java
package in.bench.resources.java8.offsetdatetime.examples;
import java.time.OffsetDateTime;
import java.time.ZoneOffset;
public class CheckOffsetDateTimeIsAfterAnotherOffsetDateTime {
public static void main(String[] args) {
// 1. get Local Offset Date/time
ZoneOffset zoneOffsetLocal = ZoneOffset.of("+05:30");
OffsetDateTime currentOffsetDateTime = OffsetDateTime
.of(2022, 8, 15, 12, 30, 30, 500, zoneOffsetLocal);
System.out.println("1. Current Offset Date/time is = " + currentOffsetDateTime);
// 2. form Past Offset Date/time
ZoneOffset zoneOffsetPast = ZoneOffset.of("+10:30");
OffsetDateTime pastOffsetDateTime = OffsetDateTime
.of(2022, 8, 15, 12, 30, 30, 500, zoneOffsetPast);
System.out.println("2. Past Offset Date/time is = " + pastOffsetDateTime);
// 3. form Future Offset Date/time
ZoneOffset zoneOffsetFuture = ZoneOffset.of("-09:30");
OffsetDateTime futureOffsetDateTime = OffsetDateTime
.of(2022, 8, 15, 12, 30, 30, 500, zoneOffsetFuture);
System.out.println("3. Future Offset Date/time is = " + futureOffsetDateTime);
// 4. isAfter() - LocalDateTime comparison
System.out.println("\n\n4. Comparing 2 LocalDateTime using isAfter() method :- \n");
// 4.1 check whether currentOffsetDateTime isAfter futureOffsetDateTime

// 5. isAfter() - self LocalDateTime comparison
System.out.println("\n\n5. Self comparing LocalDateTime using isAfter() method :- \n");
// 5.1 check whether currentOffsetDateTime isAfter currentOffsetDateTime

// 5.3 check whether futureOffsetDateTime isAfter futureOffsetDateTime
boolean isAfter9 = futureOffsetDateTime.isAfter(futureOffsetDateTime);
System.out.print("5.3 Future Offset Date/time (" + futureOffsetDateTime

}
}
