Data Structures in Java: Part 5, The Core Collection Interfaces

The Java Collections Framework defines six core interfaces, in two distinct trees. Learn the inheritance structure and the purpose of those interfaces. Learn how the interfaces declare polymorphic methods that apply to implementations of the interfaces and learn about the optional methods of the Collection interface.

Preface

This is the fifth lesson in a miniseries on Java data structures and the Java Collections Framework. The first lesson in the miniseries was entitled Data Structures in Java: Part 1, Getting Started. The previous lesson was entitled Data Structures in Java: Part 4, Purpose of Implementations and Algorithms.

The purpose of this miniseries is to help you learn the essential features of Object-Oriented data structures in Java using the Collections Framework.

Viewing tip

You may find it useful to open another copy of this lesson in a separate browser window. That will make it easier for you to scroll back and forth among the different listings while you are reading about them.

Supplementary material

I recommend that you also study the other lessons in my extensive collection of online Java tutorials. You will find those lessons published at Gamelan.com. However, as of the date of this writing, Gamelan doesn't maintain a consolidated index of my Java tutorial lessons, and sometimes they are difficult to locate there. You will find a consolidated index at Baldwin's Java Programming Tutorials...

Baldwin shows you how to extract the contents of a collection into an array, and how to use a Comparator object to sort the contents of the array into reverse natural order. He also shows you how to sort the contents of the array into natural order without the use of a Comparator object.
