[Fix] Instant java.time.temporal.UnsupportedTemporalTypeException: Unsupported unit: Years


Unsupported unit Years
Unsupported unit Years

If you have created an object of Instant class from the Java Date and Time API and you are trying to add or subtract Years from it you will get this error!

Exception in thread "main" java.time.temporal.UnsupportedTemporalTypeException: 

Unsupported unit: Years

	at java.base/java.time.Instant.plus(Instant.java:861)
	at org.code2care.JavaInstantClassExample.main(JavaInstantClassExample.java:13)
Reason:

Instant class deals with time in seconds/milliseconds and epoch time and does not deal with a date.

Solution:

You will need to convert the instant to a LocalDateTime and then add units like years.
