Java进阶之工厂模式（一）简单工厂模式

abstract class Human{        //定义一个人类的抽象类
public abstract void eat();        //声明三个方法
public abstract void sleep();
public abstract void beat();
}

class Man extends Human{
public void eat(){
System.out.println("Man can eat!");
}

public void sleep(){
System.out.println("Man can sleep !");
}

public void beat(){
System.out.println("Man can beat doudou !");
}
}

class Female{
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 doudou !");
}
}

public class HumanFactory{
public static Human createHuman(String gender){
Human human=null;        //声明一个对象
if("Man".equals(Man)){
human=new Man();    //实例化人类
}else if("Female".equals(Female)){
human=new Female();
}
return human;
}
}

public class Godness{
public static void main(String[] arges){
Human human=HumanFactory.createHuman("man");
human.eat();
human.sleep();
human.beat();
}
}
