Question
Which of the following is a generic interface in the Java Collection Framework?Question 4Answera.Listb.Setc.Mapd.Iterable
Solution
All of the options provided (List, Set, Map, Iterable) are generic interfaces in the Java Collection Framework.
Here's a brief explanation of each:
a. List: The List interface is an ordered collection that can contain duplicate elements. You can access elements by their index, which starts from 0.
b. Set: The Set interface is an unordered collection of objects, in which duplicate values cannot be stored. It models the mathematical set abstraction.
c. Map: The Map interface maps unique keys to values. A key is an object that you use to retrieve a value at a later date. It's not technically part of the Collection framework, but it's fully integrated with it.
d. Iterable: The Iterable interface is the root interface for all the collection classes. The Collection interface extends the Iterable interface and therefore all the subclasses of Collection interface also implement the Iterable interface. It allows an object to be the target of the "for-each loop" statement.
