Strategy | Behavioural Design Pattern | Intent, Examples, UML, Code & Trade-Offs

In this video, we dive deep into the Strategy Pattern, a behavioral design pattern that allows you to choose algorithms or behaviors dynamically at runtime.

What you'll learn:
Intent: How the Strategy Pattern enables flexibility by separating behavior into interchangeable strategies.
Real-World Use Cases: Implementing Payment Methods (e.g., Credit Card, UPI, Net Banking) with a Shopping Cart class as the context.
Visualizing with Diagrams:
Sequence Diagram: How the Shopping Cart interacts with various payment strategies.
Class Diagram: The structure of strategies, context, and their relationships.
Code Walkthrough: Practical implementation showcasing how to dynamically switch between payment strategies in a shopping cart system.
Trade-Offs: Evaluate the strengths (flexibility, code reusability) and weaknesses (increased complexity) of the Strategy Pattern.
