5. Collections
A collection is a structured data type that stores data and provides
operations for adding data to the collection.

9. Collections
A collection is a structured data type that stores data and provides
operations for adding data to the collection.
Operations include:
removing data from the collection
updating data in the collection
and operations for setting and returning the values of different
attributes of the collection.

10. Collection Types
Collections can be broken down into two types: linear and nonlinear.

11. Collection Types
Collections can be broken down into two types: linear and nonlinear.
A linear collection is a list of elements where one element follows the
previous element.

12. Collection Types
Collections can be broken down into two types: linear and nonlinear.
A linear collection is a list of elements where one element follows the
previous element.
Elements in a linear collection are normally ordered by position (first,
second, third, etc.).

13. Collection Types
Collections can be broken down into two types: linear and nonlinear.
A linear collection is a list of elements where one element follows the
previous element.
Elements in a linear collection are normally ordered by position (first,
second, third, etc.).
Nonlinear collections hold elements that do not have positional order
within the collection.

14. Collection Types
Collections can be broken down into two types: linear and nonlinear.
A linear collection is a list of elements where one element follows the
previous element.
Elements in a linear collection are normally ordered by position (first,
second, third, etc.).
Nonlinear collections hold elements that do not have positional order
within the collection.
An organizational chart is an example of a non- linear collection.

Dr.Haitham A. El-Ghareeb (CIS) Data Structures and Algorithms - 2012 September 30, 2012 6 / 13

16. Collection Properties and Methods
Collection Property is the collections Count, which holds the number
of items in the collection.

17. Collection Properties and Methods
Collection Property is the collections Count, which holds the number
of items in the collection.
Collection operations, called methods, include:
Add (for adding a new element to a collection)
Insert (for adding a new element to a collection at a specified index)
Remove (for removing a specified element from a collection)
Clear (for removing all the elements from a collection)
Contains (for determining if a specified element is a member of a
collection)
