Factory Method Design Pattern: Coding ExampleIn factory method design pattern mainly three classes/interfaces are involved, first, the factory class that creates an object from a given class hierarchy, second, an interface which is implemented by the concrete classes; objects of those classes will ...
ExampleThe Factory Method defines an interface for creating objects, but lets subclasses decide which classes to instantiate. Injection molding presses demonstrate this pattern. Manufacturers of plastic toys process plastic molding powder, and inject the plastic into molds of the desired shapes. The ...
Some important points about Factory Design Pattern method are; We can keep Factory class Singleton or we can keep the method that returns the subclass asstatic. Notice that based on the input parameter, different subclass is created and returned.getComputeris the factory method. Here is a simple...
Super class in factory pattern can be an interface, abstract class or a normal java class. For our example, we have super class as abstract class with overriddentoString()method for testing purpose. Sub Class1 (CrunchifyEbay.java) Notice that the class is extending CrunchfiyCompany class. ...
看了论坛上的文章,读FactoryMethod Pattern UML图,写了个小例子程序。做为文章的补充! //Creator.java public abstract class Creator { /** * looks like a factory * contains some products and some process methods */ protected Product duct;
抽象产品Fruit.java package com.DesignPattern.Creational.FactoryMethod; public interface Fruit { //生长 public void grow(); //收获 public void harvest(); //栽种 public void plant(); } 详细工厂FruitAppleGardener.java package com.DesignPattern.Creational.FactoryMethod; ...
在Java 中应用设计模式 - Factory Method刘湛
The Factory method works just the same way: it defines an interface for creating an object, but leaves the choice of its type to the subclasses, creation being deferred at run-time. A simple real life example of the Factory Method is the hotel. When staying in a hotel you first have to...
