测试代码:
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);
}
