Object-oriented programming, or OOP, is an approach to problem-solving
where all computations are carried out using objects.
An object is a component of a program that knows how to perform certain actions and how
to interact with other elements of the program.
Objects are the basic units of object-oriented programming.
A simple example of an object would be a person.
Logically, you would expect a person to have a name.
This would be considered the property of the person.
You could also expect a person to be able to do something, such as walking or driving.
This would be considered a method of the person.
- The class is a model or blueprint or prototype of an object that defines or specifies all the properties & behavior of the objects.
- An object is an entity or instance of a class.
- Each object has properties and behaviors.
- Polymorphism refers to the ability to process objects differently depending on their data type or class.
- Abstraction means hiding the implementation and showing only functionality to the user.
- Encapsulation is the process of binding the data by making it private and functions to process that data into a single unit.
