Study Notes
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
