Collections Framework
Introduction
In this wiki, we are going to talk about collections frameworks : their history, the advantages of standard collections frameworks (like Java), compared to that of C++, the advantages of collections built into languages like Ruby compared to those having collections as class libraries. We will illustrate the advantages and compare the differences with some examples.
What is a collections framework?
A collection is a group of objects, and is essentially a container that groups multiple elements into a single unit.
