Polymorphic reference Exception question

(from SCJP for Java 5 by Kathy Sierra and Bet Bates, page 104)

class Animal{
public void eat() throws Exception{
// throws an exception
class Dog2 extends Animal{
public void eat(){ //no Exceptions{
public static void main(String[] args){
Animal a = new Dog2();
Dog2 d = new Dog2();;;

Question: The book says that the code will not compile because of the Exception declared on the Animal eat() method.

I do not understand why this is. Could somebody please help. Thank you in advance.

Please do not cross-post the same question in multiple forums. It wastes people's time when multiple redundant conversations take place. Please read this for more information.
