ArrayList containing different objects of the same superclass - how to access method of a subclass

Question

Hi I\'m wondering if there is a simple solution to my problem,

I have an ArrayList:

ArrayList  animalList = new          


        

Answer 1

You dont need to do any casting. The overridden method should get called [simple polymorphism]

Animal aAnimal==  this.animalList.get(animalIndex);
aAnimal.move();

Above code should call bird method if object is of bird, isn't it?

And casting is not a solution , how will you decide which object to cast? You will have to use instanceOf.
