java工厂方法模式学习

总结；定义一个接口，多个实现类，一个工厂方法

public interface Human {
    void eat();
    void sleep();
}

public class WhiteHuman implements Human{
    @Override
    public void eat() {
        System.out.println("白种人吃饭");
    }

    @Override
    public void sleep() {
        System.out.println("白种人睡觉");
    }
}

public class YellowHuman implements Human{
    @Override
    public void eat() {
        System.out.println("黄种人吃饭");
    }

    @Override
    public void sleep() {
        System.out.println("黄种人睡觉");
    }
}

public class HumanFactory {
    public static Human createHuman(Class tClass) {
        try {
            return (Human) Class.forName(tClass.getName()).newInstance();
        } catch (InstantiationException e) {
            throw new RuntimeException(e);
        } catch (IllegalAccessException e) {
            throw new RuntimeException(e);
        } catch (ClassNotFoundException e) {
            throw new RuntimeException(e);
        }

    }
}
