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 ...
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...
Factory Method: creation through inheritance. Prototype: creation through delegation. Often, designs start out using Factory Method (less complicated, more customizable, subclasses proliferate) and evolve toward Abstract Factory, Prototype, or Builder (more flexible, more complex) as the designer discovers...
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 ...

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. ...
In this example we have a factory method,AbstractFactoryMethod, that specifies the function,makePHPBook($param). The concrete classOReillyFactoryMethodfactory extendsAbstractFactoryMethod, and can create the correct the extension of theAbstractPHPBookclass for a given value of$param. ...
设计模式(5)-Factory Method Pattern 一、 工厂方法(Factory Method)模式 工厂方法(FactoryMethod)模式是类的创建模式,其用意是定义一个创建产品对象的工厂接口,将实际创建工作推迟到子类中。 工厂方法模式是简单工厂模式的进一步抽象和推广。由于使用了多态性,工厂方法模式保持了简单工厂模式的优点,而且克服了它的缺点...
工厂方法模式（Factory Method Pattern）定义了一个用于创建对象的接口，但让子类决定实例化哪个类。接口中...
