The template method defines the steps of an algorithm and allows subclasses to provide implementations for one or more steps.
The common design algorithm is controlled directly by the implementation class, and there are duplicates in many functions similar objects. And because the organization of the class is not flexible, it is often necessary to make a lot of redundant steps when new similar modules are

The template method is a very simple design pattern with high frequency.Intention:Defining the skeleton of an algorithm in an operation, and delaying the implementation of some methods into subclasses, Templatemethod allows subclasses to redefine specific methods of the algorithm without altering the structure of the algorithm.Participants:AbstractClass, abstract class.

Recently, we have seen the shadows of design patterns in many occasions. We have been investing in algorithms and data structures for a long time. It is very important to find the design patterns. Sometimes code maintenance, reuse, and scalability are better than pure algorithms. So I picked up Daniel's book "big talk Design Patterns" and referred to the blogs of

Template method is based on the design pattern of inheritance, which can improve the scalability of the system. Abstract parent class, subclass in JavaThe template method has two parts structure, the first part is abstract parent class, the second part is the concrete implementation subclass.
