Preface

This module is one of a series of modules designed to teach you about Object-Oriented Programming (OOP) in general and the Java Collectionsframework in particular.

This module shows you how to use the more-complex version of the toArray method declared in the Collection interface. The module discusses issues regarding the type of the array and the types of the objects referred to by the elements in the collection. The module also discusses issues regarding the relative sizes of the array and the collection. Finally,the module reaffirms that you need to exercise caution when using the elements stored in the array, to avoid corrupting the state of the objects referred to by the elements in the collection.

In addition to studying these modules, I strongly recommend that you study the Collections Trail in Oracle's Java Tutorials . The modules in this collection are intended to supplement and not to replace those tutorials.
