package com.javapatterns.abstractfactory;import util.S;public class test {/** * @param args */public static void main(String[] args) {ConcreteCreatorA ConcreteCreatorA = new ConcreteCreatorA();ProductA productA1 = ConcreteCreatorA.factoryA();ProductB productB1 = ConcreteCreatorA.factoryB();ConcreteCreatorB ConcreteCreatorB = new ConcreteCreatorB();ProductA productA2 = ConcreteCreatorB.factoryA();ProductB productB2 = ConcreteCreatorB.factoryB();S.s(productA1);S.s(productA2);S.s(productB1);S.s(productB2);}}
