场景：女娲造人

抽象工厂模式

定义：为创建一组相关或相互依赖的对象提供一个接口，而且无需指定它们的具体类

场景问题解决类图：

主要涉及如下几个角色：

1.人种接口

2.白色人种

3.黄色人种

4.黑色人种

5.黄色女性人种、黑色女性人种、白色女性人种

6.黄色男性人种、黑色男性人种、白色男性人种

7.人种生成工厂接口

8.女性生成工厂

9.男性生成工厂

10.场景类

代码实现：

IHuman:

public interface Human {
	
	public void getColor();
	public void talk();
	public void getSex();

}

AbstractYellowHuman:

public abstract class AbstractYellowHuman implements Human{

	public void talk() {
		
	}
	
	public void getColor() {
		
	}
}

AbstractWhiteHuman:

public abstract class AbstractWhiteHuman implements Human {

	public void talk() {
		
		System.out.println("the white people speak english!");
		
	}
	
	public void getColor() {
		
		System.out.println("the white people skin is white!");
		
	}
}

AbstractBlackHuman:

public abstract class AbstractBlackHuman implements Human {
	
	public void talk() {
		
	}
	
	public void getColor() {
		
	}

}

FemalYellowHuman:

public class FemaleYellowHuman extends AbstractYellowHuman{

	public void getSex() {
		
	}

}

MaleYellowHuman:

public class MaleYellowHuman extends AbstractYellowHuman{

	public void getSex() {
		// TODO Auto-generated method stub
		
	}

}

HumanFactory:

public interface HumanFactory {
	
	public Human createYellowHuman();
	
	public Human createBlackHuman();
	
	public Human createWhiteHuman();

}

FemaleFactory:

public class FemaleFactory implements HumanFactory{

	public Human createYellowHuman() {
		return new FemaleYellowHuman();
	}

	public Human createBlackHuman() {
		return new FemaleBlackHuman();
	}

	public Human createWhiteHuman() {
		return new FemaleWhiteHuman();
	}

}

MaleFactory:

public class MaleFactory implements HumanFactory{

	public Human createYellowHuman() {
		return new MaleYellowHuman();
	}

	public Human createBlackHuman() {
		return new MaleBlackHuman();
	}

	public Human createWhiteHuman() {
		return new MaleWhiteHuman();
	}

}

Client:

public class NvWa {
	
	public static void main(String[] agrs) throws Exception {
		HumanFactory maleHumanFactory = new MaleFactory();
		HumanFactory femaleHumanFactory = new FemaleFactory();
		
		Human maleYellowHuman = maleHumanFactory.createYellowHuman();
		Human femaleYelloHuman = femaleHumanFactory.createYellowHuman();
		
		maleYellowHuman.getColor();
		maleYellowHuman.talk();
		maleYellowHuman.getSex();
		
		femaleYelloHuman.getColor();
		femaleYelloHuman.talk();
		femaleYelloHuman.getSex();
	    
	}

}
