普通工厂模式：

代码：

//两者共同的接口
interface Human{
    void eat();
    void sleep();
    void beat();
}

//创建实现类 Male
class Male implements Human{
    public void eat(){
        System.out.println("Male can eat");
    }
    public void sleep(){
        System.out.println("Male can sleep");
    }
    public void beat(){
        System.out.println("Male can beat");
    }
}

//创建实现类 Female
class Female implements Human{
    public void eat(){
        System.out.println("Female can eat");
    }
    public void sleep(){
        System.out.println("Female can sleep");
    }
    public void beat(){
        System.out.println("Female can beat");
    }
}

class HumanFactory{
    public Human createHuman(String gender){
        if(gender.equals("male")) {
            return new Male();
        }else if(gender.equals("female")){
            return new Female();
        }else{
            System.out.println("请输入正确的类型！ ");
            return null;
        }
    }

}

// 工厂测试类
public class FactoryTest {
    public static void main(String[] args){
        HumanFactory factory = new HumanFactory();
        Human male = factory.createHuman("male");
        male.eat();
        male.sleep();
        male.beat();
    }
}
