Help in generics

[jose chiramal]

Hi, Could someone please help me understand the below concept :

"An ArrayList<Animal> can accept references of type Dog, Cat, or any other subtype of Animal (subclass, or if Animal is an interface, implementation)."


Additionally could someone please point me to understand any good link for understanding the concepts used in Generics.

In simple terms, if there is a reference like "ArrayList<Animal> anim", you can add a dog, cat, cow, or any other animal into that object, using the add(-) method. You may have a look at the Sun Generics tutorial.
