what are the four components of object-oriented design?
user
the four components of object-oriented design are abstraction, encapsulation, inheritance and polymorphism. abstraction is the process of creating a representation of a real-world entity or problem that highlights the important details and eliminates irrelevant data. encapsulation is the packaging of data and methods that act on the data into a single unit or object. inheritance helps to reduce the duplication of code and promote reusability by allowing classes to inherit behavior from a parent class. polymorphism allows for different objects of the same type to respond to the same message, in different ways.
