[原]工廠方法模式

工廠方法模式的核心是一個抽象工廠類,而簡單工廠模式把核心放在一個具體類上.工廠方法模式可以允許很多具體工廠類從抽象工廠類中將創建行爲繼承下來,從而可以成爲多個簡單工廠模式的綜合,進而推廣了簡單工廠模式

interface Person{   
    public abstract void love();   
    public abstract void like();   
}   

class Boy implements Person{   
    public void love(){   
        System.out.println("男孩愛女孩");   
    }   
    public void like(){   
        System.out.println("男孩喜歡讓女孩天天開心");   
    }   
}   

class Girl implements Person{   
    public void love(){   
        System.out.println("女孩也愛男孩");   
    }   
    public void like(){   
        System.out.println("女孩希望男孩天天陪着她");   
    }   
}   

class Man implements Person{   
    public void love(){   
        System.out.println("男人愛錢也愛女人");   
    }   
    public void like(){   
        System.out.println("男人更喜歡能擁有一輛自己的車");   
    }   
} 

class Woman implements Person{   
    public void love(){   
        System.out.println("女人也愛男人");   
    }   
    public void like(){   
        System.out.println("女人更喜歡男人有錢");   
    }   
} 

interface AbstractFactory{

}

class AdultFactory implements AbstractFactory{
	public Person getAdult(String type){

public class FactoryDemo{   
    public static void main(String[] args) {   
        AdultFactory cf = new AdultFactory();
    	//MinorsFactory bf = new MinorsFactory();
        Person c = null;
        c = cf.getAdult("Woman");
        //c = bf.getMinors("Boy");
        c.love();
        c.like();
    }
