Disadvantages of Object-Oriented Programming (OOP)

Increased Complexity for Small Projects

Overhead of class design:

OOP requires defining classes, even for simple tasks.
This can lead to unnecessary complexity when a simple script or function would suffice.

Example

Imagine a calculator program that only adds two numbers.
Using OOP might involve creating classes like Calculator, with methods for each operation with different access modifiers.
In contrast, a procedural approach could achieve the same result with a single function.

Longer development time:

Designing classes, methods, and relationships can increase development time, especially for small-scale projects.

Note

OOP is most beneficial for large projects with complex requirements.
For small tasks, the overhead of class design may outweigh the benefits.

Steep learning curve:

OOP requires a solid understanding of concepts like encapsulation, inheritance, and polymorphism, which can be challenging for beginners.
