Back to Question 20

Answer 19

True. Unlike a collection that implements the Set interface, a collection that implements the List interface is typically allowed to contain duplicate values.

Back to Question 19

Answer 18

False. A collection that implements the List interface is an ordered collection (also known as a sequence) . According to Oracle, "The user of the interface has precise control over where in the list each element isinserted." Elements can be inserted and retrieved on the basis of their integer index (position in the list) using the following methods:
