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 Java4020: What is a Collection .

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.

Question 8

True or False? Object's references are always stored in a collection as type Collection .

Answer 8

Question 9

True or False? When a method receives an incoming parameter as type Collection, the method can call (on the reference to the Collection object) any of the methods declared in the Collection interface, with confidence that the behavior of the method will be appropriate for the actual type of Collection object involved. (That is polymorphic behavior.)

Answer 9

Question 10

True or False? The Iterator interface is one of the core collection interfaces.

Answer 10

Question 11

True or False? The core collection interfaces are shown below, with indentation showing the superinterface-subinterface relationships among the interfaces.

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

Answer 11

Question 12

True or False? Each of the following classes provides an implementation of one of the interfaces that make up the Java Collections Framework. (See the Java documentation.)
