Advantages of OOP:
- Modularity: Code is divided into independent objects, simplifying development and maintenance.
- Code reuse: Inheritance and polymorphism allow existing code to be used in new contexts.
- Flexibility: Polymorphism enables objects of different types to respond to the same messages differently.
- Complexity management: Encapsulation hides implementation details, reducing interaction complexity between components.
- Better structure: Allows modeling real objects and their relationships.
Disadvantages of OOP compared to procedural programming:
- Steeper initial learning curve: Concepts of classes, objects, inheritance require time to master.
- Performance overhead (sometimes): Virtual method calls can be slightly slower than direct procedure calls.
Disadvantages of OOP compared to functional programming:
- Object state: Changing an object's state can lead to unpredictable consequences and complicate debugging (side effects).
- Parallelism complexity: Managing object states in a multithreaded environment requires additional effort (e.g., synchronization).
- Less expressive for some tasks: For data transformation tasks, functional approach is often more concise.
Comparison of main concepts:
| Concept | Procedural Programming | Object-Oriented Programming | Functional Programming |
|---|---|---|---|
| Main unit | Procedure/Function | Object (data + behavior) | Function (data transformation) |
| Flow control | Sequential execution, branching, loops | Method calls on objects | Function composition |
| State | Can change globally | Encapsulated within objects | Immutable data |
| Reuse | Code copying, procedure calls | Inheritance, polymorphism | Function composition |
