【软件架构】软件体系结构风格实现

要求：

       麦当劳（McDonalds）和肯德基（KFC）快餐店都经营汉堡（Hamburg）和可乐（Cola），用面向对象思想实现这两个快餐店经营产品的抽象工厂模式。绘制该模式的UML类图。

代码实现：

//AbstractFactory.java

interface AbstractFactory{Hamburg createHamburg();Cola createCola();
}

//Cola.java

public interface Cola{void getCola();
}

//Hamburg.java

public interface Hamburg {void getHumburg();
}

//KFCCola.java

public class KFCCola  implements Cola{public void getCola() {System.out.println("KFCCola");}
}

//KFCFactory.java

public class KFCFactory implements AbstractFactory{public Hamburg createHamburg() {return new KFCHamburg();}public Cola createCola() {return new KFCCola();}}

//KFCHamburg.java

public class KFCHamburg implements Hamburg{public void getHumburg() {System.out.println("KFCHamburg");}}

//Main.java

public class Main {public static void main(String[] args) {Hamburg h = null;Cola c = null;AbstractFactory af = null;af = new McDonaldsFactory();h = af.createHamburg();c = af.createCola();h.getHumburg();c.getCola();af = new KFCFactory();h = af.createHamburg();c = af.createCola();h.getHumburg();c.getCola();}
}

//McDonaldsCola.java

public class McDonaldsCola implements Cola{public void getCola() {System.out.println("McDonaldsCola");}	
}

//McDonaldsFactory.java

class McDonaldsFactory implements AbstractFactory{public Hamburg createHamburg() {return new McDonaldsHamburg();}public Cola createCola() {return new McDonaldsCola();}
}

//McDonaldsHamburg.java

class McDonaldsHamburg implements Hamburg{public void getHumburg() {System.out.println("McDonaldsHamburg");}
}

类图：
