NEED: An intersect for 2 Arraylists : I've got 2 arraylists and i want to find common elements from those 2.

Example:

Arraylist 1 contains: "Cat", "Dog", "Phone", "Watch", "Monkey".

Arraylist 2 contains: "Dog", "Phone", "Chair".

As a result i want to have a method which returns : "Dog" and "Phone".

I've used an Array before and the intersect worked with the array, but im using an arraylist now.

Can anyone help me?

Kind regards,

Niels
