In programming, the word "framework" generally refers to a structure underlying a system that can be used within the system to perform a set of similar operations. Thus, we can think of a framework as a collection of libraries/APIs.
Similarly, the collections framework provides developers with a set of APIs to perform common data/data structure-related operations (which can be called data operations). The collections framework contains a few of the most commonly needed interfaces to deal with data structures and their common concrete implementations. You can always create your own custom implementation of a Collection interface. The collections framework also defines the most common algorithms, including the following:
- Searching
- Sorting
- Insertion
- Deletion
- Manipulation
All the lists, maps, and sets we use in our programs every day are part...
