The document provides an overview of object-oriented analysis and design concepts including: objects, classes, encapsulation, inheritance, polymorphism, and messaging. Classes define objects that have attributes and behaviors. Encapsulation involves collecting attributes into classes and hiding some attributes. Inheritance allows subclasses to inherit attributes and methods from parent classes. Polymorphism enables the same message to have different behaviors depending on the receiving object's class.

4. 1 - 3
Object-Oriented Programming
Object-oriented programming (OOP) is a way to organize and
conceptualize a program as a set of interacting objects.
The programmer defines the types of objects that will exist.
The programmer creates object instances as they are
needed.
The programmer specifies how these various object will
communicate and interact with each other.
5. 1 - 4
What is an Object?
Real-world objects have attributes and behaviors.
Examples:
Dog
Attributes: breed, color, hungry, tired, etc.
Behaviors: eating, sleeping, etc.
Bank Account
Attributes: account number, owner, balance
Behaviors: withdraw, deposit
6. 1 - 5
Software Objects
Writing software often involves creating a computational model
of real-world objects and processes.
Object-oriented programming is a methodology that gives
programmers tools to make this modeling process easier.
Software objects, like real-world objects, have attributes and
behaviors.
Your best bet is to think in terms as close as possible to the
real world; trying to be tricky or cool with your system is
almost always the wrong thing to do (remember, you can’t
beat mother nature!)
7. 1 - 6
Software Objects - Cont’d
In object-oriented languages,
they are defined together.
An object is a collection of
attributes and the behaviors
that operate on them.
Variables in an object are called
attributes.
Procedures associated with an
object are called methods.
In traditional programming languages (Fortran, Cobol, C, etc)
data structures and procedures are defined separately.
Account
Account
Account
balance:
number:
Bank
deposit()
withdraw()
8. 1 - 7
Classes
The definitions of the attributes and methods of an object are
organized into a class. Thus, a class is the generic definition
for a set of similar objects (i.e. Person as a generic definition
for Jane, Mitch and Sue)
A class can be thought of as a template used to create a set
of objects.
A class is a static definition; a piece of code written in a
programming language.
One or more objects described by the class are instantiated
at runtime.
The objects are called instances of the class.
9. 1 - 8
Classes - Cont’d
Each instance will have its own distinct set of attributes.
Every instance of the same class will have the same set of
attributes;
every object has the same attributes but,
each instance will have its own distinct values for those
attributes.
10. 1 - 9
Bank Example
The "account" class describes the
attributes and behaviors of bank
accounts.
The “account” class defines two
state variables (account number
and balance) and two methods
(deposit and withdraw).
class: Account
deposit()
withdraw()
balance:
number:
11. 1 - 10
Bank Example - Cont’d
When the program runs there will
be many instances of the account
class.
Each instance will have its own
account number and balance
(object state)
Methods can only be invoked .
balance: $240
number: 712
balance: $941
number: 036
balance: $19
number: 054
Instance #1
Instance #2
Instance #3
12. 1 - 11
Encapsulation
When classes are defined, programmers can specify that
certain methods or state variables remain hidden inside the
class.
These variables and methods are
accessible from within the class, but not
accessible outside it.
The combination of collecting all the
attributes of an object into a single class
definition, combined with the ability to hide
some definitions and type information
within the class, is known as
encapsulation.

13. 1 - 12
Graphical Model of an Object
State variables make up the nucleus of the object. Methods
surround and hide (encapsulate) the state variables from the
rest of the program.
theBalance

accountNumber()
balance()
Instance

Methods
deposit()

14. 1 - 13
Instance Methods and Instance Variables
The methods and variables described in this module so far are
know as instance methods and instance variables.
These state variables are associated with the one instance of
a class; the values of the state variables may vary from
instance to instance.
Instance variables and instance methods can be public or
private.
It is necessary to instantiate (create an instance of) a class to
use it’s instance variables and instance methods.
15. 1 - 14
Class Methods and Class Variables
In addition to instance methods and instance variables, classes
can also define class methods and class variables.
These are attributes and behaviors associated with the class
as a whole, not any one instance.
Class variables and class methods can be public or private.
It is not necessary to instantiate a class to use it’s class
variables and class methods.
16. 1 - 15
Class Variables
A class variable defines an attribute of an entire class.
In contrast, an instance variable defines an attribute of a
single instance of a class.
count: 3

num: 712
bal: $240
num: 036
bal: $941

17. 1 - 16
Inheritance
The advantage of making a new class a subclass is that it will
inherit attributes and methods of its parent class (also called
the superclass).
Subclasses extend existing classes in three ways:
By defining new (additional) attributes and methods.
By overriding (changing the behavior) existing attributes and
methods.
By hiding existing attributes and methods.
18. 1 - 17
Subclasses
When a new class is developed a programmer can define it to
be a subclass of an existing class.
Subclasses are used to define special cases, extensions, or
other variations from the originally defined class.
Examples:
Terrier can be defined as a
subclass of Dog.
SavingsAccount and
CheckingAccount can be
derived from the Account
class (see following slides).
Generic Class for
Dog
With general
attributes and
behaviors for all
dogs.
Specific Class for
Terrier
With new attributes
and behaviors
specific to the
Terrier breed.
Terrier is derived
from Dog
19. 1 - 18
New Account Types - Cont’d
Suppose we define SavingsAccount and CheckingAccount
as two new subclasses of the Account class.
class Account {
method acctNum()
{…}
method balance() {…}
method deposit() {…}
method withdraw()
{…}
}
class SavingsAccount
extends Account {
method rate() {…}
}
class CheckingAccount
extends Account {
method withdraw() {…}
}
20. 1 - 19
New Account Types - Cont’d

acctNum()
balance()
withdraw()
deposit()
acctNum()
balance()
withdraw()
deposit()
acctNum()
balance()
withdraw()
rate() withdraw()
Account CheckingAccount
SavingsAccount
No new code has to be written for deposit() and other
methods, they are inherited from the superclass.
21. 1 - 20
Messages
Messages are information/requests that objects send to other
objects (or to themselves).
Message components include:
The name of the object to receive the message.
The name of the method to perform.
Any parameters needed for the method.
Manager Employee
Message
To: Employee
Method: getHired
Parameters: salary = $45,000, start_date = 10/21/99
22. 1 - 21
Benefits of Messages
Message passing supports all possible interactions between
two objects.
Message passing is the mechanism that is used to invoke a
method of the object.
Objects do not need to be part of the same process or on the
same machine to interact with one another.
Message passing is a run-time behavior, thus it is not the
same as a procedure call in other languages (compile-time).
The address of the method is determined dynamically at run-
time, as the true type of the object may not be known to the
compiler.
23. 1 - 22
Polymorphism
Polymorphism is one of the essential features of an object-
oriented language; this is the mechanism of decoupling the
behavior from the message.
The same message sent to different types of objects results
in:
execution of behavior that is specific to the object and,
possibly different behavior than that of other objects receiving
the same message.
Example: the message draw() sent to an object of type
Square and an object of type Circle will result in different
behaviors for each object.
24. 1 - 23
Polymorphism – Cont’d
There are many forms of Polymorphism in object-oriented
languages, such as:
True Polymorphism: Same method signature defined for different
classes with different behaviors (i.e. draw() for the Classes Circle
and Square)
Parametric Polymorphism: This is the use of the same method
name within a class, but with a different signature (different
parameters).
Overloading: This usually refers to operators (such as +,-,/,*, etc)
when they can be applied to several types such as int, floats,
strings, etc.
Overriding: This refers to the feature of subclasses that replace
the behavior of a parent class with new or modified behavior.
25. 1 - 24
OO Concepts Summary
Object-oriented programming is a way of conceptualizing a
program as groups of objects that interact with one another.
A class is a general template used to create objects.
The combination of collecting all the attributes of an object into a
single class definition, combined with the ability to hide some
definitions within the class, is known as encapsulation.
Classes can also define class variables and class methods which
are attributes and methods associated with the class as a whole.
Inheritance allows classes to “inherit” attributes and methods from
their base (parent) class. This provides a clean mechanism for
code re-use and extension.

27. 1 - 26
Software Lifecycles
Software lifecycles describe the evolution of a software
project from conception of the need for a software system to
the retirement or replacement of the resulting system.
Two key dimensions of a specific lifecycle are:
The collection of activities to be done
The flow or sequencing of those activities
28. 1 - 27
Common Lifecycle Activities
Project Charter (definition): General description or problem
statement, top level business scenarios.
Analysis: Systems level, low detail, problem space oriented.
Results in Requirements/Specification document.
Design: Implementation level, high detail, solution space
oriented. Results in Software design/model document.
Implementation: Coding, testing, UI, data design,
documentation. Results in deliverable product.
Delivery: Configuration, training, maintenance, product
evolution planning.
Product end of life planning: Replacement
29. 1 - 28
Common Lifecycle Flows
Lifecycle flows (there are just about as many of these as there
are software projects…) can generally be characterized as one
of the following types:
Sequential
Waterfall method, Structured Analysis & Design
Iterative, Spiral and Recursive Methods
There are a huge variety of these
“Agile” or “LightWeight” Software Methods fit into this class
Parallel Effort
Unmanaged, Chaotic

Use Cases
Use cases describe the basic business logic of an application.
Use cases typically written in structured English or Diagrams
Represent potential business situations of an application
Describes a way in which a real-world actor – a person, organization,
or external system – interacts with the application.
For example, the following would be considered use cases for a
university information system:
Enroll students in courses
Output seminar enrolment lists
Remove students from courses
Produce student transcripts.
35. 1 - 34
Class Responsibility Collaborator Cards
A CRC model is a collection of CRC cards that represent
whole or part of an application or problem domain
The most common use for CRC models is to gather and
define the user requirements for an object-oriented
application
The next slide presents an example CRC model for a
shipping/inventory control system, showing the CRC cards as
they would be placed
Note the placement of the cards: Cards that collaborate with
one another are close to each other, cards that don’t
collaborate are not near each other

38. 1 - 37
Sequence Diagrams
Traditional sequence diagrams show:
The objects involved in the use case
The messages that they send each other
Return values associated with the messages
Sequence diagrams are a great way to review your work as
they force you to walk through the logic to fulfill a use-case
scenario and match the responsibilities and collaborators in
CRC cards.
40. 1 - 39
Class Diagrams
Class diagrams (object models) are the mainstay
of OO modeling
They are used to show both what the system will be able to
do (analysis) and how it will be built (design)
Class diagrams show the classes of the system and their
interrelationships
Inheritance
Aggregation
Associations
43. 1 - 42
OOA/OOD Exercise # 1
This exercise is to learn an object-oriented analysis and design
(OOA/OOD) methodology known as responsibility driven
design.
Using the real world structure of a instant teller machine, model the
objects involved (attributes and behaviors) and their relationships (who
sends messages to whom).
Each object is represented on a 3x5 note card.
You focus on identifying the various responsibilities that are needed for
the operation of an instant teller system and who (what object) should
implement those responsibilities.
This is much like laying out an organizational flow chart. Layout the
cards on the table or tape them on a wall. Re-arrange, add new cards
and throwaway cards until it looks and feels “right” to you.
