Object-Oriented Concepts
Attribute: the basic data of the class.
Method (operation): an executable procedure that is encapsulated in a class and is designed to
operate on one or more data attributes that are defined as part of the class.
Object: when specific values are assigned to all the resources defined in a class, the result is an
instance of that class. Any instance of any class is called an object.
This all is about the object oriented programming in c++ language. It includes the importent components of oops , related terminologies and the related details.

The objective of Student information System is to allow the administrator
of any organization to edit and find out the personal details of a student and
allows the student to keep up to date his profile .It’ll also facilitate keeping
all the records of students, such as their id, name, mailing address, phone
number, DOB etc. So all the information about an student will be available
in a few seconds.
Overall, it’ll make Student Information Management an easier job for the
administrator and the student of any organization. The main purpose of this SRS document is to illustrate the requirements of the project Student information System and is intended to help any organization to maintain and manage its student’s personal data.

Project 2
Introduction - the SeaPort Project series
For this set of projects for the course, we wish to simulate some of the aspects of a number of Sea Ports.
Here are the classes and their instance variables we wish to define:
SeaPortProgram extends JFrame
o variables used by the GUI interface
o world: World
Thing implement Comparable <Thing>
o index: int
o name: String
o parent: int
World extends Thing
o ports: ArrayList <SeaPort>
o time: PortTime
SeaPort extends Thing
o docks: ArrayList <Dock>
o que: ArrayList <Ship> // the list of ships waiting to dock
o ships: ArrayList <Ship> // a list of all the ships at this port
o persons: ArrayList <Person> // people with skills at this port
Dock extends Thing
o ship: Ship
Ship extends Thing
o arrivalTime, dockTime: PortTime
o draft, length, weight, width: double
o jobs: ArrayList <Job>
PassengerShip extends Ship
o numberOfOccupiedRooms: int
o numberOfPassengers: int
o numberOfRooms: int
CargoShip extends Ship
o cargoValue: double
o cargoVolume: double
o cargoWeight: double
Person extends Thing
o skill: String
Job extends Thing - optional till Projects 3 and 4
o duration: double
o requirements: ArrayList <String>
// should be some of the skills of the persons
PortTime
o time: int
Eventually, in Projects 3 and 4, you will be asked to show the progress of the jobs using JProgressBar's.
2
Here's a very quick overview of all projects:
1. Read a data file, create the internal data structure, create a GUI to display the structure, and let
the user search the structure.
2. Sort the structure, use hash maps to create the structure more efficiently.
3. Create a thread for each job, cannot run until a ship has a dock, create a GUI to show the
progress of each job.
4. Simulate competing for resources (persons with particular skills) for each job.
Project 2 General Objectives
Project 2 - Map class, Comparator, sorting
Use the JDK Map class to write more efficient code when constructing the internal data
structures from the data file.
Implement SORTING using the Comparator interface together with the JDK support for sorting
data structures, thus sorting on different fields of the classes from Project 1.
Extend the GUI from Project 1 to let the user sort the data at run-time.
Documentation Requirements:
You should start working on a documentation file before you do anything else with these projects, and
fill in items as you go along. Leaving the documentation until the project is finished is not a good idea for
any number of reasons.
The documentation should include the following (graded) elements:
Cover page (including name, date, project, your class information)
Design
o including a UML class diagram
o classes, variables and methods: what they mean and why they are there
o tied to the requirements of the project
User's Guide
o how would a user start and run your pro ...
Similar to Advanced software engineering lab 2 (20)
Software engineering task bridging the gap between system requirements engineering and software design.
Provides software designer with a model of:
system information
function
behavior
Model can be translated to data, architectural, and component-level designs.
Expect to do a little bit of design during analysis and a little bit of analysis during design.
1. LAB 2-INTRODUCTION
BS-III (ADVANCED S/W ENG.)
Object-Oriented Concepts
Attribute: the basic data of the class.
Method (operation): an executable procedure that is encapsulated in a class and is designed to
operate on one or more data attributes that are defined as part of the class.
Object: when specific values are assigned to all the resources defined in a class, the result is an
instance of that class. Any instance of any class is called an object.
Discovering Classes
Discovering and defining classes to describe the structure of a computerized system is not an
easy task. When the problem domain is new or unfamiliar to the software developers it can
be difficult to discover classes; a cookbook for finding classes does not exist.
Classes Categories
Classes are divided into three categories:
Entity: models information and associated behavior that is long-lived, independent of the
surrounding, application independent, and accomplishes some responsibility
Boundary: handles the communication between the system surroundings and the inside of the
system, provides interface, and facilitates communication with other systems
Control: model sequencing behavior specific to one or more use cases. Control classes
coordinate the events needed to realize the behavior specified in the usecase, and they are
responsible for the flow of events in the use case
Exercise 1(identification of classes)
Consider the following requirements for the Video Store system. Identify the candidate
classes: The video store keeps in stock an extensive library of current and popular movie
titles. A particular movie may be held on video tape or disk. Video tapes are in either "Beta"
or "VHS" format. Video disks are in DVD format. Each movie has a particular rental period
(expressed in days), with a rental charge to that period. The video store must be able to
immediately answer any inquiries about a movie's stock availability and how many tapes
and/or disks are available for rental. The current condition of each tape and disk must be
known and recorded. The rental charge differs depending on video medium: tape or disk (but
it is the same for the two categories of tapes: Beta and VHS).The system should accommodate
future video storage formats in addition to VHStapes, Beta tapes and DVD disks. The
employees frequently use a movie code, instead of movie title, to identify the movie. The
same movie title may have more than one release by different directors. You may use any (or
mix) of the class elicitation methods to find the candidate classes.
2. Following two exercises are the programming assignments to assess the student’s ability:
Programming assignment 1
Create an inheritance hierarchy of Vehicle: Car, Bus and Truck, with the School Bus further
extending the hierarchy through the Bus. Each of the derived class objects should be
packaging information about category and passenger carrying capacity of that vehicle.
Provide a method that is common to all derived classes, such as getPassengerCapacity (),
with class Truck having an additional method called getLoadingCapacity () that should be
returning that truck's loading capacity in tons. Create objects of all the derived classes in a
test class and store the references in an array (4 Elements) of type Vehicle, the top-level class
of this hierarchy. Provide logic so that at every run of the program any one of the four
references stored in the array is randomly selected and the methods of that object are called
polymorphically. Every random access must result in display of category and passenger
carrying capacity of that particular vehicle, except in the case of a Truck object, where the
call must result in the display of category, passenger carrying capacity and the cargo loading
capacity.
Programming assignment 2
In this assignment you are required to do some string processing. Consider the English word
"CONTAMINATION". This word consists of 13 letters. However, some of the letters occur
more than once. There are ONLY 7 DISTINCT letters occurring in the string which are {A,
C, I, M, N, O, T}. So, although, the total number of letters in the word is 13, there are ONLY
7 DISTINCT letters of the English alphabet in the string. Similarly, consider the word
"RETREAT". It consists of 7 letters. However, there are only 4 DISTINCT letters in it which
are {A, E, R, T}. Similarly the word "NEEDLE" consists of 6 letters but it contains ONLY 4
DISTINCT letters which are {D, E, L, E}. Now consider the word "FLASHING". It consists
of 8 letters. But since no letter is repeated, the number of DISTINCT letters occurring in it is
ALSO 8. Similarly the number of DISTINCT letters occurring in the word "PROMISE" is
the SAME (7) as the TOTAL number of letters occurring in it.
Write program which inputs a word (having not more than 15 letters) from the
keyboard and displays the number of DISTINCT letters occurring in it.
