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 ...

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;

Creator 一般为抽象类,声明若干factory method(方法),由它创建类型为Product的对象。正因为它能"生产"对象,所以称为factory method。Creator也可能拥有一个方法创建某个缺省的具体对象。 ConcreteCreator 重载factory method以创建某个 ConcreteProduct 的具体实例。
program to the factory class. Let’s first learn how to implement a factory design pattern in java and then we will look into factory pattern advantages. We will see some of the factory design pattern usage in JDK. Note that this pattern is also known asFactory Method Design Pattern. ...
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...
