SUMMARY OF THE PROJECT

Today all the work at the time of admission of the students is done manually by ink

and paper, which is very slow and consuming much efforts and time.

It is required to Design of a Computerized Automated Student Admission System,

to speed up and make it easy to use system.

The Student Walkin Form, an application developed in CORE JAVA is designed to store student

data during admission process so as to make the admission procedure easy and error free.

University wants to computerize its admission process for higher education courses. The aim of

the proposed system is to address the limitations of the current system. The requirements for the

system have been gathered from the defects recorded in the past and also based on the feedback

from users of previous metrics tools. Following are the objectives of the proposed system:

Reducing time in activities. Reduce the time taken process the applications of students,

admitting a student, verify student marks etc.

Centralized data handling. Transfer the data smoothly to all the departments involved and

handle the data centralized way.

Paperless admission with reduced manpower. Reduce the manpower needed to perform all the

admission and administration task by reducing the paper works needed.

Cost cutting. Reduce the cost involved in the admission process.

Operational efficiency. Improve the operational efficiency by improving the quality of the process.

MODULE

Admin users - Has full access to all the modules of this system. Responsible for the accounts of

all students, colleges and remittances.

PROJECT FEATURES

P a g e | 6

User Interface:

Soothing Graphical User Interface

Totally Menu Driven

All reports for specified period selected using report

DATABASE SCHEME :

1) Studentinfo Table :

This table stores the member information.

OBJECTIVE

The main goal of the system is to automate the process carried out in the organization with

improved performance and realize the vision of paperless admission. Some of the goals of the

system are listed below:

1) Manage large number of student details.

2) Manage all details of student who registered for the course .

3) Create student accounts and maintain the data’s effectively.

4) View all the details of the students.

5) Manage the details of hostellers and facilitate the allotment of hostels rooms for the students.

7) Reduce the work load in interview the students for selection and Counseling should be very

effective rather then direct methods. Activities like updating, modification, deletion of records

should be easier.

PROJECT SCOPEThis project’s aim is to automate the system, pre-checking the inclusion of all required material

and automatically ranking each student’s application based on a number of criteria. These criteria

include the ranking of their university, their grade at said university and their language grade

P a g e | 7

Certificate. The data used by the system is stored in a database that will be the centre of all

information held about students and the base for the remainder of the process after the initial

application has been made. This enables things to be simplified and considerably quickened,

making the jobs of the people involved easier. It supports the current process but centralizes it

and makes it possible for decisions to be made earlier and easier way.

TOOLS USED FOR DEVELOPMENT:

The tools used for the Project Development:

1) JAVA Development Kit 6.0

2) Microsoft Access 2007 as the Database.

INTRODUCTION TO THE PROGRAMMING ENVIRONMENT

JAVA

Java is related to C++, which is a direct descendent of C.This programming languge was

originally developed by Sun Microsystems and released in 1995 as a core component of Sun

Microsystems' Java platform. Sun released the first public implementation as Java 1.0 in 1995. It

promised "Write Once, Run Anywhere" (WORA), providing no-cost run-times on popular

platforms. Fairly secure and featuring configurable security, it allowed network- and file-access

restrictions. Major web browsers soon incorporated the ability to run secure Java applets within

web pages, and Java quickly became popular. With the advent of Java 2, new versions had

multiple configurations built for different types of platforms.

The main features of Java are that

1) It is platform Independent.

P a g e | 8

2) It is complete Object Oriented.

3) In this pointers are not available.

4) Java applications are typically compiled to byte code that can run on any JVM(Java Virtual

Machine) regardless of computer architecture. These applications are portable. The

applications are such which needs to be compiled once and executed any number of times .

Java has been categorized into 3 parts:

1.) Core Java: It includes basics of Java(basically system software can be implemented and run

on LAN, Converters, Compressors, Zip Files etc.

2).Advanced Java: It is used for web Application(internet-Websites, intranet e.g. ATM machine).

3).Enhanced Java: It is the extended version of java.

FEATURES OF JAVA

P a g e | 9

1. Platform Independent: The Write-Once-Run-Anywhere ideal has not been achieved (tuning

for different platforms usually required), but closer than with other languages. Java programs are

operating system independent.

2. Object Oriented: Java is object oriented throughout i.e. there is no coding outside of class

definitions, including main(). There is an extensive class library available in the core language

packages.

3. Compiler/Interpreter Combination: Code is compiled to bytecodes that are interpreted by a

Java virtual machines (JVM). This provides portability to any machine for which a virtual

machine has been written. The two steps of compilation and interpretation allow for extensive

code checking and improved security.

4. Dynamic Binding: The linking of data and methods to where they are located, is done at run-

time. New classes can be loaded while a program is running. Even if libraries are recompiled,

there is no need to recompile code that uses classes in those libraries. This differs from C++,

which uses static binding.

5. Robust: a) Automatic Memory Management (by JVM)

b) Exception handling built-in, strong type checking (that is, all data must be declared an explicit type), local variables must be initialized.

6. Several Dangerous Features of C and C++ Eliminated: No memory pointers are used as they increase the complexity and insecurity.

7. Threading: Threads are Lightweight processes which helps in performing multiprocessing. We can take advantage of multiprocessors where available

8. Automatic Memory Management: Automatic garbage collection - memory management handled by JVM.

9. Security:

9.1) No memory pointers.

9.2) Programs run inside the virtual machine sandbox.

9.3) Array index limit checking

P a g e | 10

10. High Performance: Interpretation of bytecodes slowed performance in early versions, but

advanced virtual machines with adaptive and just-in-time compilation and other techniques now

typically provide performance up to 50% to 100% the speed of C++ programs.

JAVA ENVIRONMENT

Java environment includes large number of development tools and hundreds of classes and

methods. The development tools are part of the system known as Java Development Kit (JDK)

and the classes and methods are part of the Java Standard Library (JSL), also known as the

Application Programming Interface (API).

Java swings class hierarchy:

JPanel is Swing's version of the AWT class Panel and uses the same default layout, FlowLayout.

JPanel is descended directly from JComponent.

JFrame is Swing's version of Frame and is descended directly from that class. The components

added to the frame are referred to as its contents; these are managed by the contentPane. To add

a component to a JFrame, we must use its contentPane instead.

JLabel, is used to create text labels.

JTextField allows editing of a single line of text. New features include the ability to justify the

text left, right, or center, and to set the text's font.

JTextArea allows editing of multiple line

JTextArea allows editing of multiple lines of text. JTextArea can be used in conjunction with

class JScrollPane to achieve scrolling. The underlying JScrollPane can be forced to always or

never have either the vertical or horizontal scrollbar;

JButton is a component the user clicks to trigger a specific action.

P a g e | 11

JChoice is like a drop down box. You can click a drop-down arrow and select an option from a

list. For example, when the component has focus, pressing a key that corresponds to the first

character in some entry's name selects that entry. A vertical scrollbar is used for longer lists.

FlowLayout when used arranges swing components from left to right until there's no more space

available. Then it begins a new row below it and moves from left to right again. Each component

in a FlowLayout gets as much space as it needs and no more.

BorderLayout places swing components in the North, South, East, West and center of a

container. You can add horizontal and vertical gaps between the areas.

GridLayout is a layout manager that lays out a container's components in a rectangular grid.

The container is divided into equal-sized rectangles, and one component is placed in each

rectangle.

Line Border and Titled Border provides border. These are used in conjunction with buttons

and labels. Titled Border is used to assign title.

Java awt class hierarchy:

The Java AWT (Abstract Windowing Toolkit) contains the fundamental classes used for

constructing GUIs. The abstract Component class is the base class for the AWT. Many other

AWT classes are derived from it. Button, Canvas, and Container are some AWT classes derived

from Component. The JComponent class is derived from Container and is one of the base classes

of Swing. The JFrame class is derived from the AWT Frame class. It is usually the main

container for a GUI application. The JApplet class (derived from the AWT Applet class) is

sometimes used for Web programming, but the Applet class is more frequently used.

Exception Handling In JAVA

A program can use exceptions to indicate that an error occurred. To throw an exception, use the

throw statement and provide it with an exception object to provide information about the specific

P a g e | 12

error that occurred. A method that throws an uncaught, checked exception must include a throws

clause in its declaration.

A program can catch exceptions by using a combination of the try, catch, and finally blocks. The

try block identifies a block of code in which an exception can occur. The catch block identifies a

block of code, known as an exception handler, can handle a particular type of exception. The

finally block identifies a block of code that is guaranteed to execute, and is the right place to

close files, recover resources, and otherwise clean up after the code enclosed in the try block.

The try statement should contain at least one catch block or a finally block and may have

multiple catch blocks.

The class of the exception object indicates the type of exception thrown. The exception object

can contain further information about the error, including an error message. With exception

chaining, an exception can point to the exception that caused it, which can in turn point to the

exception that caused it, and so on.

SQL (STRUCTURED QUERY LANGUAGE)

SQL (Structured Query Language, is a database computer language designed for the retrieval

and management of data in relational database management systems (RDBMS), database schema

creation and modification, and database object access control management.

The SQL language is sub-divided into several language elements, including:.

1) Queries which retrieve data based on specific criteria.

2)Expressions which can produce either scalar values or tables consisting of columns and

rows of data.

3) Clauses, which are in some cases optional, constituent components of statements and

queries.

4) Whitespace is generally ignored in SQL statements and queries, making it easier to

P a g e | 13

format SQL code for readability.

5) SQL statements also include the semicolon (";") statement terminator. Though not

required on every platform, it is defined as a standard part of the SQL grammar.

6) Predicates which specify conditions that can be evaluated to SQL logic Boolean truth

values and which are used to limit the effects of statements and queries, or to change

program flow.

QUERIES

The most common operation in SQL databases is the query, which is performed with the

declarative SELECT keyword. SELECT retrieves data from a specified table, or multiple related

tables, in a database. It is often grouped with Data Manipulation Language (DML) statements, as

it has no persistent effects on the data stored in a database.

SQL queries allow the user to specify a description of the desired result set, but it is left to the

devices of the database management system (DBMS) to plan, optimize, and perform the physical

operations necessary to produce that result set in as efficient a manner as possible. An SQL

query includes a list of columns to be included in the final result immediately following the

SELECT keyword. An asterisk ("*") can also be used as a "wildcard" indicator to specify that

all available columns of a table (or multiple tables) are to be returned. SELECT is the most

complex statement in SQL, with several optional keywords and clauses, including:

1) The “FROM” clause which indicates the source table or tables from which the data is

to be retrieved.

2) The “WHERE” clause includes a comparison predicate, which is used to restrict the

number of rows returned by the query.

3) The “GROUP BY” clause is used to combine, or group, rows with related values into

P a g e | 14

elements of a smaller set of rows.

4) The “HAVING” clause includes a comparison predicate used to eliminate rows after

the GROUP BY clause is applied to the result set

5) The “ORDER BY” clause is used to identify which columns are used to sort the

resulting data, and in which order they should be sorted (options are ascending or

descending).

DETAILS OF THE WORK PROGRAM

My six weeks work program at SQL Technologies from June, 2010 to July 20010 included the

following topics:

1) Introduction to Java: Under this we were taught the difference between C Language and Java

and the difference between C++ and Java. This section also included the features of java and the

java buzzwords like simple, object oriented, multithreaded, architecture-neutral, high

performance, distributed etc.

2) Overview of Java: This included the abstraction and the OOPS principles. Along with this we

were taught how to write a simple java program. The control statement and the lexical issues

were also covered under this heading.

3) Data Types and Operators: The various data types in java like integer, floating type, characters

etc, variables and arrays were taught. Operators included arithmetic operators, bitwise operators,

relational operators, logical operators, assignment operators and ‘?’ operator.

4) Introducing classes: We were taught the basic class fundamentals and how to declare objects.

Methods were also introduced. The various types of constructors were covered and the this

keyword introduced.

5)Methods and Classes: Method overloading, constructor overloading, static keyword, final

keyword, nested and inner classes and how to use command line arguments were taught.

6) Inheritance: The inheritance basics, different types of inheritance, method overriding, abstract

classes and the use of the final keyword were covered under this heading.

7) Packages and Interfaces: Defining a package and access protection was discussed. Defining

and implementing an interface were taught. This is a very important application used in the

project. Varios packages have been constructed and imported wherever necessary.

8)Exceptional Handling: The exception types, using try and catch, multiple catch clauses, nested

try statements, throw, throws and finally keyword and programs using exceptional handing were

taught. Invalid entries, invalid cursor positions, wrong password, busy connections etc are all

handled using the exceptional handing concepts.

9) Event Handling: The ActionEvent and the MouseEvent classes were discussed. These classes

include methods to handle external events. The ActionListener interface and the MouseListener

P a g e | 24

interface have been extensively used in the project to handle mouse clicks, button clicks, mouse

movements etc.

10)Introducing the AWT and the SWING: Window fundamentals(frame , panel etc), working

with frames, controls, layouts, labels, text boxes, password fields, buttons, check boxes,

checkbox groups, dialog boxes, etc were taught. The knowledge of these have been used in the

project to make a graphical use interface. There tools have been used to make the usage of the

software easy, convenient and user friendly. Actions are performed on button clicks making the

work of the user simple and easily understandable.

FEASIBILITY STUDY

Technical Feasibility

This deals with computer resources and infrastructure. Technical feasibility revolves around the

existing computer system (hardware, software etc.) and to what extent it can support the

proposed system. For example, if the current computer is operating at 80% capacity then running

another application could overload the system or require additional resources. This project is

technically feasible as it is based on the existing technology which is in widespread use. Now the

proposed system will be able to run on the existing hardware and the required software. So the

proposed system is technically feasible.

Economic Feasibility

This estimates whether the proposed system would be financially justified. Economics is most

frequently used for the effectiveness of the proposed system. More commonly known as cost

benefit analysis, the procedure is to determine the comparison between benefits and savings that

are expected from the proposed system and costs. If benefits outweigh costs, then the decision is

made to design and implement the system. Otherwise, further justifications or alterations will

have to be made.

Operational Feasibility

This is in order to know whether the proposed system will be user friendly and error-free in it’s

functioning. People are inherently resistant to changes, and computers have been known to

facilitate changes. The proposed system is very much user friendly and easy to navigate therefore

there is no need for special training and guidance.

TESTING

Various types of input data were entered in the system to test the system so that the system

accepts only valid and correct data. If the user enters an illegal value or invalid data he/she is

interrupted either by exceptions or by message dialog boxes. This does not effect the working of

the system but informs the user for invalid data and gives another chance to the user to enter the

information again.

New Walkin Page : In this, as all the fields are required to be filled, if any field kept

empty message is displayed and user is asked to enter the complete information. Also user id

filled by user is checked for availability, as it should not match with any other existing user id.

For the numeric Text box :

Roll No.

The User is restricted to Input only Numerics in Numeric TextBox. He can’t enter the data in

this textbox other than numeric data.

For non numeric text boxes:

1) Name

2) Father’s name

The User is restricted to Input only Alphabets in alphabetical TextBox. He can’t enter the data in

this textbox other than alpahbets and blank space.

Check for empty fields:

In this, as all the fields are required to be filled, if any field kept empty message is displayed and

user is asked to enter the complete information

P a g e | 28

CONCLUSION

‘STUDENT WALKIN FORM’ is developed considering the requirements of common people.

The software fulfills most of the basic requirements of the user. The system is cost efficient and

no additional training is required to work on the software.

FUTURE SCOPE

The project is easily extensible and can be improved further by introducing new features like fee

deposition and mess management which is not included yet. The database can further be refined

by adding all the requirements.
