Object Oriented Programming Concepts

Practice flashcards based on key concepts from the Object Oriented Programming lecture notes.

What defines an object in an object-oriented environment?

An object is a real-world element that has an identity, state, and behavior.

What is a class in object-oriented programming?

A class represents a collection of objects with common characteristic properties and behaviors.

What is instantiation in the context of classes?

Instantiation is the creation of an object as a member of a class.

What are encapsulation and data hiding?

Encapsulation is the binding of attributes and methods within a class, while data hiding is protecting class data from direct outside access.

Define inheritance in object-oriented programming.

Inheritance allows new classes to be created from existing classes, permitting the new classes to inherit attributes and methods from super-classes.

What is polymorphism in object-oriented programming?

Polymorphism allows operations to be performed in different ways depending on the context or instance they are operating upon.

What do generalization and specialization refer to in object-oriented design?

Generalization combines common characteristics to form a super-class, while specialization creates specialized subclasses from existing classes.

What is an association in object-oriented design?

Association is a connection through which an object collaborates with other objects, depicting relationships between objects of classes.

What is aggregation in object-oriented programming?

Aggregation is a relationship where a class is composed of one or more classes, with those classes able to exist independently.

What benefits does the object model offer in software development?

It enables faster development, easy maintenance, supports upgrades, and reduces development risks.
