本文深入解析抽象工厂模式中的关键组件：创建者接口和具体创建者类，以及它们创建的不同产品类实例。通过代码示例，详细阐述了如何实现和使用抽象工厂模式来解耦创建过程。

Creator

package com.javapatterns.abstractfactory;

public interface Creator {
	public ProductA factoryA();

	public ProductB factoryB();
}

ProductA

package com.javapatterns.abstractfactory;

public interface ProductA {

}

ProductB

package com.javapatterns.abstractfactory;

public interface ProductB {

}

package com.javapatterns.abstractfactory;

public class ConcreteCreatorA implements Creator {

	public ProductA factoryA() {
		// TODO Auto-generated method stub
		return new ConcreteProductA1();
	}

	public ProductB factoryB() {
		// TODO Auto-generated method stub
		return new ConcreteProductB1();
	}

}

package com.javapatterns.abstractfactory;

public class ConcreteCreatorB implements Creator {

	public ProductA factoryA() {
		// TODO Auto-generated method stub
		return new ConcreteProductA2();
	}

	public ProductB factoryB() {
		// TODO Auto-generated method stub
		return new ConcreteProductB2();
	}

}

package com.javapatterns.abstractfactory;

public class ConcreteProductA1 implements ProductA{

}

package com.javapatterns.abstractfactory;

public class ConcreteProductA2 implements ProductA{

}

package com.javapatterns.abstractfactory;

public class ConcreteProductB1 implements ProductB{

}

package com.javapatterns.abstractfactory;

public class ConcreteProductB2 implements ProductB{

}

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);
	}
