Exam 11: Object-Oriented Programming: Inheritance

When creating derived classes,you must use discretion in choosing the proper base class.Ideally,the base class will not contain excessive capabilities or information.

Constructors are not inherited.

A derived class can effect state changes in base class private members only through public,protected,internal methods provided in the base class and inher ited into the derived class.

Which of the following is not a base/derived class relationship

Base class methods with this level of access cannot be called from derived classes.

Inheritance is the process of building a class with object references of other classes.

The default implementation of method ToString of object returns a string representing ________.

An object of one class cannot be an object of another class.

A derived class cannot access the members of its base class.

A base class may have only one derived class.

Identify which of the following examples could be considered a base class for the Computer class

Inheritance is represented by a(n)________ relationship.

To enhance performance and reduce errors,it's a good idea to make derived classes larger than they need to be.

Method Equals will accurately compare any two objects.

The process of abstraction allows you to focus on the commonalities among objects in the system.

A method must be declared __________ for it to be overridden by derived classes.

Which of the following classes is the root of the class hierarchy

Which statement is true when a base class has protected instance variables

The default Equals implementation determines:

When a base class method is overridden in a derived class,it is common to have the derived class version call the base class version and do some additional work.
