CHAPTER 53B — Comparable Interface

Chapter Topics:

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 since numbers 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.


Arrange these strings in order: "orange", "apple", "plum".
