Which of the following is the root interface of the Java collections framework?Group of answer choicesCollectionsListCollectionIterable

Breakdown of the Problem

We need to identify the root interface of the Java collections framework from the given options.

Relevant Concepts

In Java, the collections framework is a unified architecture for representing and manipulating collections. The root interface in this framework is crucial as it defines the basic contract for all collection classes.

Analysis and Detail

The given options are:

1. Collections - This is a utility class that consists exclusively of static methods and is not an interface.
2. List - This is an interface for ordered collections (also known as sequences) and is a subtype of Collection.
3. Collection - This is indeed the root interface in the Java collections framework. It is the main interface that all collection classes implement.
4. Iterable - This interface allows an object to be the target of the "foreach" statement, but it is not the root interface of the collections framework.

Verify and Summarize

Only the Collection interface serves as a superclass for other collections such as Set, List, and Queue. To verify this, we can refer to the official Java documentation which clearly states that Collection is the root interface.

Final Answer

The root interface of the Java collections framework is Collection.
