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

In this video, we explore the State Pattern, a behavioral design pattern that lets an object alter its behavior when its internal state changes. What you'll learn: Intent: Understand how the State Pattern helps in managing state transitions cleanly and effectively. Real-World Use Cases: Jira Tickets: Seamlessly transition between "To-Do," "In Progress," and "Done" states. Document Editors: Change toolbar functionality based on the document state (e.g., Read-Only vs. Edit Mode). Music Players: Different behaviors for playing, paused, and stopped states. Visualizing with Diagrams: Sequence Diagram: Capturing the interaction between the context and state objects during transitions. Class Diagram: Depicting the State interface, concrete state classes, and the context. Code Walkthrough: Implementation of Jira Ticket transitioning through To-Do, In Progress, and Done states. Trade-Offs: Strengths: Promotes Single Responsibility Principle, simplifies code for complex state transitions, and enhances maintainability. Weaknesses: Can increase the number of classes and make state logic scattered across multiple files. Resources: UML Diagrams: https://drive.google.com/drive/folder...
