Preface

This module is one in a collection of modules on Java Collections designed for teaching ITSE2321 - Object-Oriented Programming (Java) at Austin Community College in Austin, TX.

This module contains review questions and answers keyed to the module titled Java4060: Duplicate Elements, Ordered Collections, Sorted Collections, and Interface Specialization .

Once you study that module, you should be able to answer the review questions in this module.

The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Questions

Question 1 .

True or False? The Java Collections Framework defines eight core interfaces, in two distinct trees.

Answer 1

Question 2

True or False? All eight of the core interfaces are rooted in the interface named Collection .

Answer 2

Question 3

True or False? A Set object can contain duplicate elements, but a List object cannot contain duplicate elements.

Answer 3

Question 4

True or False? The TreeSet class is a direct implementation of the Collection interface. (See the Java documentation.)

Answer 4

Question 5

True or False? The interface hierarchy for the Java Collections Framework is shown below with indentation used to show a parent-child relationship:

  • Collection
    • Set
      • SortedSet
    • List
    • Queue
    • Deque
  • Map
    • SortedMap

Answer 5

Question 6

True or False? The ArrayList class is a direct implementation of the Collection interface. (See the Java documentation.)

Answer 6

Question 7

True or False? In Java, a Set is a collection that contains no duplicate elements. The Set interface models the mathematical set abstraction.

Answer 7

Question 8

True or False? In Java, a List is an ordered collection (also known as a sequence) . The user of the List interface has precise control over where in the list each element is inserted. The user canaccess elements by their integer index (position in the list) , and search for elements in the list.

Answer 8

Question 9

True or False? The term ordered is a synonym for sorted .

Answer 9

Question 10

True or False? An ordered collection is one in which the position of each element is determined by its value relative to the values of itspredecessors and successors.

Answer 10

Question 11

True or False? A sorted collection is one in which the position of each element is determined by its value relative to the values of itspredecessors and successors.

Answer 11

Question 12

True or False? Ascending sort order is always required for a Java collection.

Answer 12

Question 13

True or False? Ascending sort order is always required for a Java collection that implements the SortedSet interface.
