Object oriented programming is a great way to organize your code, and it can be beneficial for larger projects.
OOP (object oriented programming) is a popular programming paradigm based on the concept of “objects.” In OOP, data and behaviors are bundled into objects, which can be manipulated as a single unit.
The Benefits of OOP
There are many benefits to using OOP in your programming projects. Some of the key benefits include:
- Allows you to create modular code, making it easier to understand and maintain your codebase.
- Can help you organize your code in a more efficient way, which can be especially useful for larger projects.
- Makes it easier to reuse code, saving you time and effort.
- Popular choice for many developers because it allows for more modular code, and it can be easier to understand and maintain than some other programming paradigms.
OOP Terminology, Concepts, and Principles
In OOP, there are a few key terms that you should know:
Objects
In OOP, data and behaviors are bundled into objects. An object can be thought of as a self-contained unit with its own set of data and methods.
Classes
A class is a template for creating objects. When you create an object, you are instantiating a class.
Attributes
An attribute is data that is associated with the object. For example, if you have an employee object, it might have attributes like name and salary.
Methods
A method is a function that can be called on an object to perform some action or computation. Methods are used to manipulate data and objects.
Inheritance
OOP allows you to create subclasses that inherit attributes and methods from a parent class. This allows for more modular code, and it can help improve maintainability over time by allowing developers to reuse existing classes when building new ones.
Polymorphism
OOP supports polymorphism, which means using the same method name on different objects. OOP allows for more efficient code reuse and abstraction by allowing methods to be called with different types of arguments (which may or may not have similar implementations).
Object oriented programming can also provide a more intuitive structure for your code, and it can help improve maintainability over time by allowing developers to reuse existing classes when building new ones.
Encapsulation
Encapsulation refers to the idea of bundling data and methods together into an object. OOP can help improve security by keeping private information hidden from users or other objects within your application.
OOP can also provide a more intuitive structure for your code, and it can help improve maintainability over time by allowing developers to reuse existing classes when building new ones. Object oriented programming will enable you to create subclasses that inherit attributes and methods from a parent class.
Abstraction
OOP allows for abstraction, which means that you can hide the details of an object from other objects in your code. This can be useful for creating more efficient and concise code.
Object oriented programming also allows you to create interfaces that other objects can interact with your data.
OOP Best Practices
When working with OOP, there are a few best practices to keep in mind:
- Try to use classes and objects wherever possible. This can help improve the readability and maintainability of your code.
- Keep your object data private whenever possible. This can help reduce the chances of someone tampering with your data or causing errors.
- Make methods public when you want them to be accessed by other objects in your application. OOP can also provide a more intuitive structure for your code, and it can help improve maintainability over time by allowing developers to reuse existing classes when building new ones.
- OOP supports polymorphism, which means using the same method name on different objects.
- Try to avoid inheritance whenever possible. Inheritance is an excellent tool if used correctly, but it can be challenging to manage when not used properly.
OOP Languages
- Python
- Java
- C++
OOP vs. Procedural Programming Paradigms
Procedural programming focuses on breaking down problems into smaller steps, while OOP encourages modularity and code reuse. Object oriented programming also allows for abstraction, which means that you can hide the details of an object from other objects in your code.
This can be useful for creating more efficient and concise code.
OOP in the Real World – Applications of OOP Outside of Computer Science
Now that we have a basic understanding of OOP let’s take a look at some applications outside of computer science. Object oriented programming can be used in many different fields, including but not limited to:
- Web Development
- Electronics
- Mechanical Engineering
- Mathematics
- Biology
- Economics
- Robotics
- Database Development
- Mobile Application Development
- Game Development
