What is the difference between object-oriented programming and procedural programming?

Procedural programming can use looping and branching, but object-oriented programming cannot.

Procedural programming uses subroutines, but object-oriented programming does not allow them.

Procedural programming specifies a sequence of tasks, but object-oriented programming describes the properties of tools or items.

Procedural programming specifies a sequence of calculations, but object-oriented programming involves more logic.

How does dynamic polymorphism differ from static polymorphism?

It uses inheritance instead of abstraction.

It uses overriding instead of overloading.

It uses abstraction instead of inheritance.

It uses overloading instead of overriding.

What is overriding a method?

Removing an inherited method from a subclass.

Adding a subclass method to a superclass.

Changing the name of a method.

Creating a unique version of an inherited method.

How are analysis and design different?

Analysis describes a problem; design describes a solution.

Analysis constructs; design dissects.

Analysis considers abstractions; design considers data.

Analysis describes a solution; design implements a solution.

What is the term for a visual representation of the classes in an application?

Whiteboard sketch

CRC card

Use case

Class diagram

In addition to attributes and methods, what does a UML class diagram contain?

The class name

All objects created from the class

The superclass of the subclass

Any inherited behavior

How do object behaviors and attributes differ?

Attributes apply only to a specified object, but behaviors apply to other linked objects.

Behaviors are vector quantities, but attributes are scalars.

Attributes describe a state, but behaviors describe actions.

Behaviors describe dynamic properties, but attributes are static.

Describe object interactions.

Start writing code.

Build class diagrams.

Build CRC cards.

What is the purpose of encapsulation?

To protect an object from unwanted changes

To eliminate redundant properties

To separate attributes from behaviors

To organize attributes and behaviors in a hierarchical fashion

In addition to attributes and behaviors, which quality must a class possess?

A data type

A state

A sex or color

A name

Steve is able to turn on and adjust his television even though he does not know how it works internally. This exemplifies which principle of object-oriented programming?

Abstraction

Polymorphism

Inheritance

Encapsulation

If an attribute is added to a superclass, what happens to all of the objects of the subclass?

Each subclass object must request the additional attribute.

Nothing happens to the subclass objects.

Each subclass object automatically receives the additional attribute.

Only newly created subclass objects will receive the new attribute.
