Comparable Interface
Objects that have an ordering are compared using the compareTo() method.
1. Comparable Interface
Objects of a class that implements the Comparable
interface can be arranged into a particular order. For example, objects of class String
, which implements Comparable
, can be arranged into
alphabetical order. Numeric classes such as Integer
or Double
implement Comparable
and their objects can be arranged into numeric order.
Objects of a class that implements Comparable
can be compared to each other to determine which comes first when the objects are arranged in order.
