Subject: Equivalent of collections in Java

Hi list,

I am reading the "from concepts to code" book from Jacquie Barker, but
this book uses Java as the language to learn OO programming. This
doesn't bother me at all although I'm learning Ruby, but sometimes I
don't  know if it is in Ruby and what it's called in Ruby.
I am now reading about the concept of Collections, that is Collection
objects, in Java, but I can't find something about it in my Pickaxe
book. Does someone know the equivalent in Ruby?

Also another tiny question:

I read in the Pickaxe book :  Integer(gets), how doest this work? I
thought Integer is an object type and not a method which can indeed be
called with an argument, like method(argument) ?

Thanx again,
Krekna
