Collections are used in every programming language. They are objects that group multiple elements into a single unit. Before the Collections framework, it was hard for programmers to write algorithms that worked for different kinds of collections. Java came with some Collection classes, like Vector, Stack, Hashtable, and Array, but they had their disadvantages.
In JDK 1.2, Java developers introduced the Collections framework, which is an important framework to help you achieve all of your data operations. Today, we’ll dive deeper into this framework and some of its components.
