第 6 题
阅读下列说明和 Java代码，将应填入 (n) 处的字句写在答题纸的对应栏内。 【说明】
某快餐厅主要制作并出售儿童套餐，一般包括主餐(各类比萨)、饮料和玩具，其餐品种类可能不同，但其制作过程相同。前台服务员 (Waiter) 调度厨师制作套餐。现采用生成器 (Builder) 模式实现制作过程，得到如图 6-1 所示的类图。
【Java代码】 class Pizza {
private String parts；
public void setParts(String parts) { this.parts = parts; } public String toString() { return this.parts; } }
abstract class PizzaBuilder { protected Pizza pizza;
public Pizza getPizza() { return pizza; }
public void createNewPizza() { pizza = new Pizza(); } public (1) ; }

class HawaiianPizzaBuilder extends PizzaBuilder {
public void buildParts() { pizza.setParts(\ }
class SpicyPizzaBuilder extends PizzaBuilder {
public void buildParts() { pizza.setParts(\baked + hot + pepperoni&salami\} }
class Waiter {
private PizzaBuilder pizzaBuilder;
public void setPizzaBuilder(PizzaBuilder pizzaBuilder) { /*设置构建器*/ ( 2 ) ; }
public Pizza getPizza(){ return pizzaBuilder.getPizza(); }
public void construct() { /*构建*/ pizzaBuilder.createNewPizza(); ( 3 ) ; } }
Class FastFoodOrdering {
public static viod mainSting[]args) { Waiter waiter = new Waiter();
PizzaBuilder hawaiian_pizzabuilder = new HawaiianPizzaBuilder(); ( 4 ) ; ( 5 ) ;
System.out.println(\

} }
程序的输出结果为：
Pizza:cross + mild + ham&pineapple
问题：6.1 请填写（1）（2）（3）（4）（5）
答案解析：
（1）abstract void buildParts(); （2）this.pizzaBuilder=pizzaBuilder （3）pizzaBuilder.buildParts()
（4）waiter.setPizzaBuilder(hawaiian_pizzabuilder) （5）waiter.construct()
