Software Design Patterns Questions
The Template Method design pattern is a behavioral design pattern that defines the skeleton of an algorithm in a superclass but allows subclasses to override specific steps of the algorithm without changing its structure. It provides a way to define a method in a superclass that can be customized by subclasses to provide different implementations for specific steps of the algorithm.
In this pattern, the superclass contains the template method, which is the main algorithm that calls several abstract methods. These abstract methods are implemented by the subclasses to provide their own behavior for specific steps. The template method controls the overall flow of the algorithm by calling these abstract methods in a specific order.
The Template Method design pattern promotes code reuse and allows for easy extension of the algorithm without modifying its structure. It is commonly used in scenarios where multiple classes have similar algorithms but differ in certain steps. By encapsulating the common parts in the superclass and allowing subclasses to provide their own implementations for specific steps, the Template Method pattern promotes code flexibility and maintainability.
