What are some real-world examples of the Template Method pattern?

The Template Method pattern defines the skeleton of an algorithm in a method, deferring some steps to subclasses. A common example is in software frameworks where a base class provides a template method that outlines the steps of an algorithm, while subclasses implement specific steps.

Can you give me a specific example in software development?

Sure! In a web application, a base class might define a method for processing user requests. Subclasses could implement specific request types, like handling GET or POST requests, while the base class manages the overall flow.

Are there any examples in other fields, like manufacturing?

Yes! In manufacturing, a production line might have a template method for assembling products. Different product types can have specific assembly steps, but the overall process remains consistent.

How does this pattern improve code maintainability?

The Template Method pattern promotes code reuse and separation of concerns. By defining a common structure, it reduces duplication and makes it easier to manage changes in the algorithm.
