Explore the art of code elegance as we delve into the fascinating realm of code reusability. Unveil the power of inheritance and composition, discovering the distinctive nuances that set them apart. Immerse yourself in this enlightening journey as we showcase enlightening code snippets, unraveling the secrets of creating flexible and maintainable software. Elevate your coding prowess by understanding the fine balance between inheritance and composition, making your code not just functional but truly exceptional.

1. Code Reusability

2. How to reuse code in a class again?
INHERITANCE
COMPOSITION

3. Before we start
 Composition Vs Aggregation
 Generalization vs Specialization
 Inheritance Vs composition

4. Association types
 Composition
 Is a strong association
 In UML diagram, composition is denoted by a
filled diamond.
 Aggregation
 Is a weak association
 In UML diagram, composition is denoted by an
empty diamond.
 Children can exist independently.

5. Composition Example

6. Aggregation Example

7. Generalization vs Specialization
 Generalization
 Is a mechanism for combining similar classes of
objects into a single, more general class.
 Specialization
 Is the reverse process of Generalization, which
means creating new sub-classes from an existing
class.

8. Generalization Example

9. Inheritance Vs
composition
 Both can help you reuse code.
 Inheritance establishes common behavior and interfaces
for your classes, while composition combines and reuses
existing classes to create more complex objects.
 Inheritance (is-a relationship), composition (has-a
relationship).
 Inheritance increases the coupling between a base type
and its derived types. If you change your base class, all
subclasses are also affected.
 prefer composition over inheritance
