Original: Http://www.tuicool.com/articles/6JBN7z3 If you are not yet aware of template method patterns and policy patterns, read the policy mode (strategy) and template method patterns first. The main idea of the template method pattern is to define an algorithm flow, implement the specific steps, and defer to subcla

of an algorithm. A the template method not only invokes primitive operations, it also invokes operations defined in AbstractClass or other objects. at -2. Concreteclass -Implements primitive operations to complete the steps associated with a particular subclass in the algorithm.Test class: 1 public class Test { 2 public static void main (string[] args) { 4 Temp Late temp = new Templateconcrete (); 5 Temp.update (); 6 7 } public

Template method is better understood, is to avoid code redundancy, implementation of code to take the function. For example, the most common tea and coffee, two have a lot in common, all need to boil water, all need to pour into the cup, then these repeated methods can be drawn out, placed in the parent class, as for the different methods, write an abstract class, so that different subclasses to rewrite the parent class.CodeTemplate classPackage

name of this design pattern is from here. Template Method Mode Construction: -The abstract template role has the following responsibilities: Defines one or more abstract operations to implement sub-classes. These abstract operations are called basic operations, which constitute a step of top-level logic. Defines and implements a

Template Method Mode Definition: defines the skeleton of an algorithm in an operation, and delays some steps to the subclass. The template method allows the subclass to redefine certain steps of an algorithm without changing the structure of an algorithm. For example, the exam copied by student A and student B is very similar. Except for different answers, the other questions are the same. If the instructor

I. Schema Definition The template method mode defines the skeleton of an algorithm in a method, and delays some steps to the subclass. The template method allows subclass to redefine some steps in the algorithm without changing the algorithm structure. Ii. embodied Design Principles Hollywood principle: Do not call (CALL) us. We will call (CALL) You.This principle requires that only the high-level componen

Template mode is the skeleton of an algorithm defined in a method, and some steps are deferred to subclasses, and the template method allows subclasses to redefine some of the steps in the algorithm without altering the algorithm structure.Template methods are common in many places, especially when we re-implement many frameworks, and many times we re-implement them based on the
