用人的肤色和性别进行抽象工厂方法模式的实现，肤色和性别组成产品等级结构和产品族；

具体代码实现

项目结构：

//AbstractFactory.java
package org.example.design002;

public interface AbstractFactory {
    public Man createMan();
    public Woman createWoman();
}

//YellowFactory.java
package org.example.design002;

public class YellowFactory implements AbstractFactory{
    @Override
    public Man createMan() {
        return new YellowMan();
    }

    @Override
    public Woman createWoman() {
        return new YellowWoman();
    }
}

//BlackFactory.java
package org.example.design002;

public class BlackFactory implements AbstractFactory{
    @Override
    public Man createMan() {
        return new BlackMan();
    }

    @Override
    public Woman createWoman() {
        return new BlackWoman();
    }
}

//WhiteFactory.java
package org.example.design002;

public class WhiteFactory implements AbstractFactory{
    @Override
    public Man createMan() {
        return new WhiteMan();
    }

    @Override

        AbstractFactory abf;
