OOP D.2 Features of OOP

Encapsulation

The practice of hiding the inner design of an object data type in a class, achieved in Java using the private keyword.

Data Hiding

A concept related to encapsulation that prevents other objects from accessing and possibly corrupting internal data.

Inheritance

A mechanism where one class (subclass) can inherit fields and methods from another class (superclass), forming an 'is-a' relationship.

Single Inheritance

A type of inheritance where a subclass inherits from only one superclass.

Multilevel Inheritance

A type of inheritance where a subclass is derived from another subclass, creating a chain of inheritance.

Hierarchical Inheritance

A type of inheritance where multiple subclasses inherit from a single superclass.

Polymorphism

The ability of one object or function to exhibit different attributes and behaviors depending on the context; includes method overloading.

Method Overloading

A feature that allows the same method name to be used for multiple methods distinguished by different parameter lists.

Library of Objects

A repository of reusable code that can be imported into a project, improving performance and reliability of software.

Modularity

A design principle that breaks a program into independent modules, facilitating collaboration, code reuse, and easier testing.

Pros of OOP

Encapsulation, inheritance, and polymorphism support code reuse, data protection, and modular design.

What's the cons of OOP?

Complexity, steep learning curve, and need for specialist skills.

Advantages of Code Reusability

Reduces redundancy, improves performance, and enhances reliability.

Efficiency in Programming Teams

Allows specialists to work concurrently on different areas, reducing overall development time.

Disadvantages of Library Usage in OOP

Libraries may lead to dependency issues and can complicate debugging due to abstraction.

What is the impact of Modularity on Understandability?

Systems are easier to comprehend when divided into modules, improving overall maintainability.

What are the limitations of Method Overloading?

Can lead to confusion if overloaded methods have similar signatures, making maintenance difficult.

What are the drawbacks of Learning Curve in OOP?

Maybe difficult for beginnersto grasp complex concepts, leading to slower development and increased frustration.

What are the pros of Polymorphism?

• Flexibility

• Code Reusability

• Easier Maintenance

• Supports integration
