Hi,

I have an error in eclipse when I want to write:

ArrayList ballCollection;

I imported ---> import java.util.ArrayList;

Could you help me?

Thanks.

You don't have an error, but a warning.
And you should declare it the same way we advice to declare it in Processing: with the type of the elements you plan to put in it.
See for example the Why use ArrayList instead of array with append()? article on the wiki (Technical FAQ).
