根据如下图图片，定义抽象类Animal，并在Animal类中定义一抽象方法shout()。定义Animal的两个子类Coat类和Cow类继承并重写Animal中的shout() 方法，其中Coat类中

package Chouxiangfangfa;

public class work01 {
public static void main(String[] args) {
Coat c = new Coat();
c.shot();

Cow c2 = new Cow();
c2.shot();

}
}

abstract class Animal{
abstract public void shot();
}

class Coat {
public void shot() {
System.out.println(“咪咪….”);
}
}

class Cow extends Animal{

@Override
public void shot() {
	System.out.println("咩咩");
}

}
