<strong><span style="font-size:32px;color:#3333ff;">Java多态及静态方法对动态方法的调用</span></strong>

例子：

public class FirstJava {
	 
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
	aBird a = new aBird();
	bBird b = new bBird();
	dosomething(a);
	dosomething(b);
	}
	
	static void dosomething(Bird bird){
		bird.fly();
	}		
}

abstract class Bird{<span style="white-space:pre">	</span>//创建一个父类
	 void fly() { //必须带括号
	}
}

class aBird extends Bird{<span style="white-space:pre">	</span>//子类继承父类
	void fly(){
		System.out.print("i am a abird;  ");
	}
}

class bBird extends Bird{<span style="white-space:pre">	</span>//子类继承父类
	void fly(){
		System.out.print("i am a bbird;  ");
	}	
}
