Collections

Collections
You are encouraged to solve this task according to the task description, using any language you may know.

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 (Hash)
collection = set([0, '1']) # sets (Hash)

Ruby

Ruby is a 100% object oriented language, so you can use the default Array or Hash structures as collection objects.
