Which of the following is NOT one of the four basic principles of object-oriented programming?

The principle of standardization is not one of the four basic principles of object-oriented programming (OOP). The fundamental principles of OOP include encapsulation, inheritance, polymorphism, and abstraction.

Encapsulation refers to the bundling of data and the methods that operate on that data within a single unit or class, restricting direct access to some of the object's components. This promotes data hiding and reducing complexity.

Inheritance allows a new class to inherit attributes and methods from an existing class, promoting code reuse and establishing a hierarchical relationship among classes.

Polymorphism enables objects to be treated as instances of their parent class, allowing methods to be applied to objects of different classes. This adds flexibility and the ability to extend application functionality without altering the existing code.

While standardization can be an important concept in software development, particularly in terms of coding practices and protocols, it does not directly relate to the core principles that define the structure and behavior of object-oriented programming. Understanding these four principles is crucial for building robust and maintainable object-oriented systems.
