ZoneOffsetTransition compareTo() method in Java with Example

The compareTo() method of java.time.zone.ZoneOffsetTransition class is used to make comparison between two objects of ZoneOffsetTransition type. The comparison is made based on the instants of transition.

Syntax:

public int compareTo(ZoneOffsetTransition transition)

Parameter: This method takes a transition of ZoneoffsetTransition type and compares it with this trnasition.

Return Value: This method returns zero if both the objects of the ZoneOffsetTransition are equal, a negative value if the passed transition is less than this transition and a positive value if the passed transition is greater than this transition.

Below are the examples to illustrate the compareTo() method:
