工厂模式学习报告.ppt

“设计模式”学习报告;概要:;模式概论;什么是模式 ?; 因为每一个模式描述了一个在我们周围不断重复发生的问题,以及问题的解决方案的核心,它是一种指导，在一个良好的指导下，有助于你完成任务，有助于你作出一个优良的设计方案，达到事半功倍的效果。而且会得到解决问题的最佳办法。 ; 设计模式的分类;简单工厂 (Simple Factory)模式;简单工厂模式的引论; public class Apple implements Fruit { public void grow() { System.out.println(Apple is growing...); } public void harvest() { System.out.println(Apple has been harvested.); } public void plant() { System.out.println(Apple has been planted.); } }; public class Grape implements Fruit { public void grow() { System.out.println(“Grape is growing...); } public void harvest() { System.out.println(“Grape has been harvested.); } public void plant() { System.out.println(“Grape has been planted.); } }; public class Strawberry implements Fruit { public void grow() { System.out.println( Strawberry is growing...); } public void harvest() { System.out.println( Strawberry has been harvested.); } public void plant() { System.out.println( Strawberry has been planted.); } };public class FruitGardener { public static Fruit factory(String which) throws BadFruitException { if (which.equalsIgnoreCase(apple)) { return new Apple(); } else if (which.equalsIgnoreCase(strawberry)) { return new Strawberry(); } else if (which.equalsIgnoreCase(grape)) { return new Grape(); } else { throw new BadFruitException(Bad fruit request); } } };简单工厂模式的结构;简单工厂模式的实现;简单工厂模式的优点和缺点;一个简单工厂模式的实例;工厂方法 (Factory Method)模式;工厂方法模式的引进;工厂方法模式的结构和角色;public interface Creator { public Product factory(); };活动序列图;简单工厂模式和工厂方法模式;设计模式的实际应用;FormatFactory(abstract);总结：;相关资源;Any Question?
