The difference is:Oop can handle situations where the type is unknown before the program runs.AndIn generic programming, the type can be known during compilation.. The containers, iterators, and algorithms described above are examples of generic programming. When writing a generic program, code is written independently with any specific type. When using a gen

Concreatedecorator: Add responsibilities to the component.With this decorative mode, we are in the design of the garment system, a lot of flexibility, code structure diagram: (from the big talk design mode)One of the characters is concreatecomponent,Dress class is decorator, embedded in the human pointer.The following specific clothing, that is, Concreatedecorator.

Decorative design mode:When you want to enhance the functionality of an existing object, you can customize the class, pass in existing objects, and provide enhanced functionality based on the functionality of the existing objects. Then the custom class is called the adornment class.The adornment class usually receives the decorated object by constructing the method. It provides enhanced functionality based on the functionality of the object being deco

Decorator Decorative Mode (structural mode)Subclass complex sub-class, how many subclassesJoin us we need to develop a tank for the game, in addition to different models of tanks, we also want to add a variety of features in different situations: such as infrared night vision function, such as water amphibious function, such as satellite positioning function and so on.Problem code: /// /// Abstract Tank /// Public Abstract class Tank

Problem: People need to wear clothes, can wear shoes, trousers, tie ... , the order can be made random.That is, it involves a lot of random operations, but our results require a definite order to execute the method.UML diagram:The variant of this method is that it can be decorate directly to inherit from Realcomponent.The method can be operated by the interface, which conforms to the opening and shutting principle.This enables all classes that implement the component interface to be processed us

The ability to dynamically extend an object without having to change the original class file and use inheritance. It is by creating a wrapper object, that is, decorating to wrap the real object.Characteristics:(1) The Decoration object and the real object have the same interface. This allows the client object to interact with the adornment object in the same way as the real object. (2) The Adornment object contains a reference to a real object (reference) (3) The Adornment object accepts all req

definition: dynamically adds some additional responsibilities to an object. Decorator mode is more flexible than generating subclasses in terms of adding functionality. Type: Object-structured pattern alias : Packing mode (wrapper) class Diagram: The decorator decoration pattern is a structured pattern that solves the problem of "excessive use of inheritance to extend the functionality of an object", which lacks flexibility because of the static nature introduced by the type, and as the number

Decorative design pattern.The original object is not modified to enhance the functionality of the original object.Class Person{void Chifan (){System.out.println ("eat");}}Class Newperson{private person p;Newperson (Person P){THIS.P = p;}public void Newchifan (){System.out.println ("aperitif");P.chifan ();System.out.println ("dessert");System.out.println ("Hush Hush");}}Class Persondemo{public static void Main (string[] args){Person p = new person ();P

Decorative design mode is to enhance the functionality of existing objectsSimple Small Example:classPerson {voidChifan () {System.out.println ("Chifan"); } } /*in order not to casually change the original code. Also to enhance the Chifan function. Then define a class to decorate the original object. by why ask*/ classNewperson {PrivatePerson p; Newperson (person p) { This. P =p; } Public voidNewchifan () {System.out.println ("A drink.");

Decorative design mode: Decorator pattern, also known as decorator mode. The feature is that you can dynamically add new functionality to the object without changing the class, dynamically extending it at run time. The main implementation is to implement dynamic add functionality by wrapping it into another object and adding new functionality. In other words, the original object is wrapped in another class.When implemented, you need to be aware that b
