Lab Manual for Lab based Projects

II B Tech – I Semester


Notes on lab based projects

Software projects in java are basically interconnection of various small classes inturn each class is collection of variables and methods. Every method contribute some useful output and every class purpose is separately defined. In this way by planning 3 to 4 classes and combining them through inheritance or any other means makes a lab based project. The expected behaviour from the project is called requirement, so that all the requirements are handled in the project and they are all tested for quality purpose. The requirements are two types as explained below.

1. Functional requirements: These includes how the input is accepted by the project, intermediate results, final computed outputs. All the results produced by the project.Eg. They are project sensitive

2. Non-functional requirements: These includes how you store data,

process data, what techniques are to be used to make the project. You

may consider other factors like quality, look and feel, security etc.

Eg. They are project insensitive, but basically technology specific , are

used across all the projects.

1. Use of data structures2. Using constructor overloading3. Use inheritance4. Use of final key word5. Use of abstract method6. Use of method overloading7. Use of method overriding8. Use of exception handling9. Use of encapsulation10. Use atleast one static variable and static method.11. Use of interfaces12. Use of call by reference


13. Abstract methods, classes14. Use of menu (look and feel)15. Use of password (security)16. Use of data validations (quality)

Project development life cycle :

Every project has to undergo four phases before it is

completed, namely

1. Requirements gathering : Collection of the data, procedures,

conditions, rules, expected outputs are gathered.

2. Design : Before starting the coding process necessary planning

is conducted like breaking the total projects into smaller

modules and the relations among the modules are well

planned.

3. Coding : The actual programming process begins here, each

individual modules (functions/programs) are developed

4. separately and all the programs (classes) are combined finally

to make the project.

5. Testing : Each program is tested for its validity i.e for its output

and finally the total project is also tested to confirm its outputs.


Project views:

A project can be viewed in three ways, namely

1. Data view : What data to be used, how the data to be used and

the relationships among data items are thoroughly

investigated.

2. Code view : This is pure programming, programs are developed

to work on the input data to produce the required output

according to business logic.

3. Behavioural view : This is screens designing (front end) step,

from which the data is entered into the project and the outputs

are displayed in the user friendly nature.


What a student supposed to do :

You have to choose one project from the list of projects given

in this lab manual. Each project is different by its nature, data,

behaviour. That is the data requirement ( what data is used for that

project), the conditions or constraints used to make judgements,

comparisons, intermediate computations/results and the final

outputs that produced for specific combinations of inputs.

On successful selection of a project, one has to study the

domain knowledge of the project with the help of your guide, seniors

or by using internet. This step helps you in recognising the data

requirement and functional requirements for your project.

There may be individual projects or batch wise projects depends

on the department discretion. Whatever may be the case every

student suppose to implement.

1. Any four functional requirements of your choice

2. Any eight non functional requirements of your choice


Model Project:

To help you in understanding the concept of lab based project

the course team will give you a model project. You can code walk of

this project and understand what are the functional and non

functional requirements embedded in this project. This enables you

to get ready for your project that should be submitted at the end of

semester.

Note: The above model project source code is attached at the

end of the document.

The source code of the model project is given below.

/* This is a PBL (Project based Lab) modelproject, developed by

course team of "Object Oriented Programming" @ KL University

course coordinator: Dr.MSR PRASAD

Description (Domain knowledge): There are B.Tech and M.Tech students, Students will have name, phone number and city as common data.B.Tech students have 3 sujects with pass mark as 40, where as M.Tech students have 4 subjects with pass mark as 50. minimum and maximum marks are 0 and 100 respectively.

Functional requirements:

1. All students details must be avilable as personal data and academic

data(constraint-1).

2. If anybody failed in atleast one subject result is fail,

result is pass only all subjects gets pass marks (constraint-2).

3. Howmany are the total students ?

4. Howmany are passed?

5. Howmany of them are failed?

6. Who is the top scorer?

7. Howmany marks scored by the top scorer?

8. Failed student can not be top scorer (constraint-3).


Non functional requirements:

1. Used one data structure(Array)

2. Inheritance is implemented

3. Method overloading is used

4. Method overriding is used

5. static and final key words are used

6. interface is implemnted at appropriate place.

7. call by value is used

8. call by referece is used

9. Exception handling is implemented

10.Encapsulation( use of privatekey etc. word) is used

11.data validation is done

12.Menu kind of front end is used

13.proper comments are added
