Template Method is a behavioral pattern that defines the skeleton of an algorithm in a base class, deferring some steps to subclasses. Subclasses can override specific steps without changing the overall algorithm structure. Think of a recipe: the steps are always the same (prepare ingredients → cook → plate → serve), but the specific cooking step differs for each dish. The recipe template stays fixed; only the cooking implementation varies.
ℹ️Core idea: define an algorithm as a series of steps in a final templateMethod(). Each step is a method. Common steps are implemented in the base class; variable steps are declared abstract (or as hooks) for subclasses to override.
