云南大学软件学院 实验报告课程： 设计模式实验 学期： 2010-2011学年 第一学期 任课教师： 专业： 学号： 姓名： 成绩： 实验3 装饰者模式1.题目:使用装饰着模式实现一个小吃店供应食物，然后计算费用并输出所点的食物和消费金额的程序，其中的被装饰者是粗米线、细米线、面条，装饰者是炸酱、焖肉、番茄鸡蛋以及酱油、醋、辣椒和葱花。2. 模式设计的UML类图：3.程序源代码：（1）食品抽象类FoodStuff.java：public abstract class FoodStuff String description = Unknown FoodStuff;public String getDescription()return description;public abstract double cost();（2）被装饰者的各个子类：public class ThickRicenoodles extends FoodStuff public ThickRicenoodles()description = 粗米线;public double cost()return 4.0;public class ThinRicenoodles extends FoodStuffpublic ThinRicenoodles()description = 细米线;public double cost()return 3.0;public class Noodles extends FoodStuffpublic Noodles()description = 面条;public double cost()return 2.0;（3）调味品抽象类CondimentDecorator.java：public abstract class CondimentDecorator extends FoodStuffpublic abstract String getDescription();（4）调料装饰者的各个子类：public class Firedbeansauce extends CondimentDecoratorFoodStuff foodstuff;public Firedbeansauce(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 炸酱;public double cost()return 2.0 + foodstuff.cost();public class Daube extends CondimentDecorator FoodStuff foodstuff;public Daube(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 焖肉;public double cost()return 2.0 + foodstuff.cost();public class TomatoAndEgg extends CondimentDecorator FoodStuff foodstuff;public TomatoAndEgg(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 番茄鸡蛋;public double cost()return 2.0 + foodstuff.cost();（5）佐料装饰者的各个子类：public class Soy extends CondimentDecorator FoodStuff foodstuff;public Soy(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 酱油;public double cost()return 0.0 + foodstuff.cost();public class Vinegar extends CondimentDecorator FoodStuff foodstuff;public Vinegar(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 醋;public double cost()return 0.0 + foodstuff.cost();public class Pepper extends CondimentDecorator FoodStuff foodstuff;public Pepper(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 辣椒;public double cost()return 0.0 + foodstuff.cost();public class Chives extends CondimentDecorator FoodStuff foodstuff;public Chives(FoodStuff foodstuff)this.foodstuff = foodstuff;public String getDescription()return foodstuff.getDescription() + , 葱花;public double cost()return 0.0 + foodstuff.cost();（6）实现用户界面的主类SnackBar.java：public class SnackBar extends javax.swing.JFrame public SnackBar() super(XXX);
