Question:

What is a Collection framework in Java?

Inactive
Jeremy K.
Answer:

The Collection Framework in Java contains classes and interfaces that are used to store and manipulate data in the form of objects. The Collections Framework has two interfaces—Iterable and Map. The Iterable interface gets extended by the Collections Interface, which is different from the Collection Framework, a common misconception in Java. The Collections interface is a child of the Iterable interface. The Iterable and Map interfaces make up the Collections Framework. The Collections interface is implemented by the List, Queue, and Set interfaces, each of which are extended by a class and/or implemented by one or more interfaces. The Map interface gets extended by the SortedMap interface and is implemented by the classes Hashtable, LinkedHashMap, and HashMap. The SortedMap interface is implemented by the TreeMap class.
