A collections framework is a unified architecture for representing and manipulating collections. All collections frameworks contain three things. Those three things are:

  • Interfaces
  • Implementations
  • Algorithms

Answer 13

What is the meaning of the following two images?

These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.

Spacer image of a rabbit and a penguin.

This image was also inserted for the purpose of inserting space between the questions and the answers.

Spacer image of a penguin and some houses.

Answers

Answer 13

True according to The Java Tutorial from Oracle

Back to Question 13

Answer 12

False. Iterator is not a class. It is an interface. Therefore, it has no place in the given list of classes.

Back to Question 12

Answer 11

True. With respect to an earlier question, Collection and Map are the two top-level interfaces.

Back to Question 11

Answer 10

False. While the Iterator interface is heavily used in conjunction with collections, according to The Java Tutorial from Oracle, it is not one ofthe core collection interfaces.

Back to Question 10

Answer 9

True.

Back to Question 9

Answer 8

False. Object's references are always stored as type Object .

Back to Question 8

Answer 7

False. Primitive values cannot be stored in a collection without first encapsulating them in an object. (Standard wrapper classes are provided for encapsulating all primitive types.)

Back to Question 7

Answer 6

False. The collections in the framework always store references to objects, rather than storing the objects themselves.

Back to Question 6

Answer 5

True.

Back to Question 5

Answer 4

False. Collection is one of two top-level interfaces in the framework. The other top-level interface in the framework is named Map .

Back to Question 4

Answer 3

True.
