What is the difference between Strategy and Template Pattern?

Can you explain the difference between the Strategy and Template design patterns?

Sure! The Strategy pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. The Template pattern, on the other hand, defines the skeleton of an algorithm in a method, deferring some steps to subclasses.

Can you give me an example of each pattern?

Of course! For the Strategy pattern, think of a sorting algorithm where you can choose between quicksort, mergesort, etc. For the Template pattern, consider a game where the main game loop is defined, but specific actions like player moves are implemented in subclasses.

When should I use one over the other?

Use the Strategy pattern when you need to switch algorithms at runtime. Use the Template pattern when you want to define a common structure but allow subclasses to implement specific behaviors.
