Class and Instance Quiz

Classes in Object-Oriented Programming

• A class is a blueprint or a template that defines the characteristics and behaviors of an object
• It defines the properties and methods of an object

Instance Variables

• Instance variables are data members of a class that are defined inside the class but outside any method
• Each instance of the class has its own copy of the instance variables

Classes as a Compile-Time Feature

• In certain languages, classes are only a compile-time feature, meaning they are only used during the compilation process
• The class definition is not included in the generated code, and only the resulting object code is used at runtime

Instances

• An instance is an object that is created from a class, with its own set of attributes and methods
• Each instance has its own unique set of values for its instance variables

Metaclasses

• A metaclass is a class that creates classes, allowing customization of the class creation process
• Metaclasses are classes whose instances are classes
