Collections are used to store objects and not primitive types.
Java
ArrayList arrayList = new ArrayList(); arrayList.add(new Integer(0));
PHP
$students = array(); array_push($students, array('name' => 'Joe Smith', 'age' => 21, height=> '72.5', gpa => 3.42 ));
Python
Interpreter: Python 2.5
In Python practically everything is an object, so using any of the provided structures can function as a collection.
collection = [0, '1'] # Lists by convention used for heterogenous objects collection = (0, 1) # Tuples by convention used for homogenous objects collection = {0: "zero", 1: "one"} # Dictionaries (a.k.a Hash) collection = set([0, '1'])
Ruby
Ruby is a 100% object oriented language, so you can use the default Array or Hash structures as collection objects.
