class SpicyPizzaBuilder extends PizzaBuilder{
public void buildParts(){
pizza。setParts(\} }
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*/

Class FastFoodOrdering{
public static viod mainSting[]args){
Waiter waiter = new Waiter();
PizzaBuilder hawaiian_pizzabuilder = new HawaiianPizzaBuilder(); ( 4 ) ; ( 5 ) ;
System。out。println(\。getPizza()); } }
程序的输出结果为：
Pizza:cross + mild + ham&pineapple
答案解析：
（1）abstract void buildParts(); （2）=pizzaBuilder （3）()
