Program Description Answer

List is used to store the elements in an ordered sequence and it allows duplicate elements.

Hence, the correct answer is option “A”.

Expert Solution & Answer

Explanation of Solution

List:

List is an ordered collection, which is used to order their elements by its position.
It allows duplicate elements.
New methods are defined inside the List interface.
Using “ListIterator”, a list can be inserted in both forward and backward direction.
It allows any number of null values in its collection.

Explanation for incorrect options:

b. Set:

Set is a data structure that is used for storing and processing non duplicate elements.

Hence, the option “B” is wrong.

c. Map:

Map is an interface which contains values on the basis of key and a value pair and represents a mapping between them.

Hence, the option “C” is wrong.

d.Hash set:

Hash set is used to create a collection that uses a hash table for storage.

Hence, the option “D” is wrong.
