INTRODUCTION TO JAVA

Object Oriented Programming or OOP is the technique to create programs based on the real

world. Unlike procedural programming, here in the OOP programming model programs are

organized around objects and data rather than actions and logic. Objects represent some concepts

or things and like any other objects in the real world, Objects in programming language have

certain behavior, properties, type, and identity. In OOP based language the principal aim is to

find out the objects to manipulate and their relation between each other. OOP offers greater

flexibility and compatibility and is popular in developing larger application. Another important

work in OOP is to classify objects into different types according to their properties and behavior.

So OOP based software application development includes the analysis of the problem, preparing

a solution, coding and finally its maintenance.

Java (originally called Oak) was developed because Sun was having difficulty using C++ as part

of a larger project. Java was designed to have a small footprint when it ran standalone in small

machines and devices. The Java language was derived from C++ but without many of the

cumbersome, difficult-to-use features of C++. Java's cross-platform capability originally

addressed the problem that applications for embedded devices must run on a wide variety of

hardware (without the benefit of a standardized operating system).

Java failed to capture the market in spite of a concerted push into Interactive TV. For a period,

Java looked like another good technical idea that would fail commercially.

Java Technology

Java technology is both a programming language and a platform.

The Java Programming Language

The Java programming language is a high-level language that can be characterized by all

of the following characteristics

Simple Object oriented Distributed Multithreaded Architecture neutral Portable High performance Robust

In the Java programming language, all source code is first written in plain text files

ending with the .java extension. Those source files are then compiled into .class files by the javac

compiler. A .class file does not contain code that is native to your processor; it instead contains

bytecodesthe machine language of the Java Virtual Machine1(Java VM). The java launcher

tool then runs your application with an instance of the Java Virtual Machine.

An overview of the software development process.

Because the Java VM is available on many different operating systems, the same .class

files are capable of running on Microsoft Windows, the SolarisTM

Operating System (Solaris

OS), Linux, or Mac OS. Some virtual machines, such as the Java HotSpot virtual machine,

perform additional steps at runtime to give your application a performance boost. This include

various tasks such as finding performance bottlenecks and recompiling (to native code)

frequently used sections of code.

Through the Java VM, the same application is capable of running on multiple platforms.

Types of java programs:

Applets Command line application GUI application Servlets Packages Database appplications

The Java Platform

A platform is the hardware or software environment in which a program runs. Most platforms can

be described as a combination of the operating system and underlying hardware. The Java platform differs

from most other platforms in that it's a software-only platform that runs on top of other hardware-based

platforms.

The Java platform has two components:

The Java Vir tual Machine(JVM) The Java Application Programming I nterface(API)

Java Virtual Machine is the base for the Java platform and is ported onto various hardware-based

platforms.

The API is a large collection of ready-made software components that provide many useful capabilities. It

is grouped into libraries of related classes and interfaces; these libraries are known as packages.

The API and Java Virtual Machine insulate the program from the

underlying hardware.

Every full implementation of the Java platform gives you the following features:


6/34

Development Tools: The development tools provide means for compiling, running, debugging,and documenting your applications. The main tools are the javac compiler, thejava launcher, and

thejavadoc documentation tool.

Application Programming Interface (API): The API provides the core functionality of the Javaprogramming language. It offers a wide array of useful classes ready for use in your own

applications. It spans everything from basic objects, to networking and security, to XML

generation and database access, etc.

Deployment Technologies: The JDK software provides standard mechanisms such as the JavaWeb Start software and Java Plug-In software for deploying your applications to end users.

User Interface Toolkits: The Swing and Java 2D toolkits make it possible to create sophisticatedGraphical User Interfaces (GUIs).

Integration Libraries: Integration libraries such as the Java IDL, JDBC, JNDI, Java RMI, andJava Remote Method Invocation over Internet Inter-ORB Protocol Technology (Java RMI-IIOP

Technology) enable database access and manipulation of remote objects .

Netbeans Developing Windows Application

Netbeans can be used to create professional-looking GUIs with automatic spacing and

alignment.

Professional Swing GUI BuildingDesign Swing GUIs by dragging and positioning GUI components from a palette

onto a canvas. The GUI builder automatically takes care of the correct spacing and

alignment. Click into JLabels, JButtons, ButtonGroups, JTrees, JTextFields,

ComboBoxes and edit their properties directly in place. You can use the GUI builder to

prototype GUIs right in front of customers.

Intuitive and Customizable

You can choose whether the GUI code should be generated with fully qualified or

simple class names. The help bar displays context-sensitive hints about what can be done

with the selected component and suggests shortcuts that can speed up your work in the

future. The NetBeans IDE also comes with built-in support for GUI localization and

accessibility. If you use JDK 6 Update 10, you can now preview your forms in the new

Nimbus look and feel.

Standard and Custom GUI ComponentsThe extensible Component Palette comes with pre-installed Swing and AWT

components and includes a visual menu designer. Use the Component Inspector to view a

component's tree and properties.

Swing Application Framework (JSR 296) SupportThe Swing Application Framework simplifies the handling of the application life

cycle, actions and resources. Take advantage of the provided code-generation tools and

building blocks, and develop small to medium-sized desktop applications faster than

ever. Create menus fast and intuitively by dragging and dropping menu items onto the

canvas; you can add mnemonics and rename menu items inline by clicking and typing in

the Design view.

Beans Binding technology (JSR 295) SupportTake advantage of Beans Binding technology and the Java Persistence API to

create Swing desktop database applications more easily. Using the new Java Desktop

Application project template, you can quickly set up a form that displays a database table

and also enables you to modify the database. Bind a database table to an existing form by

dragging a table from the Runtime window onto the form.

SYSTEM ANALYSIS:

EXISTINGSYSTEM:

System Analysis is a detailed study of the various operations performed by a system and their

relationships within and outside of the system. Here the key question is what all problems exist

in the present system? What must be done to solve the problem? Analysis begins when a user or

manager begins a study of the program using existing system.

During analysis, data collected on the various files, decision points and transactions

handled by the present system. The commonly used tools in the system are Data Flow Diagram,

interviews, etc. Training, experience and common sense are required for collection of relevant

information needed to develop the system. The success of the system depends largely on how

clearly the problem is defined, thoroughly investigated and properly carried out through the

choice of solution. A good analysis model should provide not only the mechanisms of problem

understanding but also the frame work of the solution. Thus it should be studied thoroughly by

collecting data about the system. Then the proposed system should be analyzed thoroughly inaccordance with the needs.


13/34

PROPOSED SYSTEM:

Proposed system is an Employee Management Software. According to designate we can create

an account, Add/Modify/Delete employee and department details. Our proposed system has the

following advantages.

User friendly Interface Fast access to database Less error Storage Capacity Search Facility Data Modification Facilities


14/34

SYSTEM DESIGN:

OUTPUT FORM DESIGN

Computer output is the most important and direct source of information to the user.

Efficient, intelligible output design should improve the system relationship with the user and

help in decision-making. The outputs provide in the system are the softcopy report available for

printing. Printouts should be designed around the output requirement of the user. The output

devices to consider depend on the factor such as compatibility of the device with the system,

response time requirement and number of copies needed.

INPUT FORM DESIGN

Input Design is the process of converting user originated computer based format.

Inaccurate input data are the most common cause of errors in data processing .Errors entered by

data entry operators can be controlled by input design. The goal of designing input data is to

make data entry as easy, logical and free from errors as far as possible. In this system, the input

screens are developed according to the user requirements.

DATABASE DESIGN

The general theme behind a database is to handle information as an integrated whole. A

database is a collection of interrelated data stored with minimum redundancy to serve many users

quickly and effectively. After designing the input and output, the analyst must concentrate on

database design or how data should be organized around user requirements. The general

objective is to make information access, easy quick, inexpensive and flexible for other users.

During database design the following objectives are concerned:-

Controlled Redundancy Easy to learn and use More information and low cost Accuracy Integrity

SUMMARY

From a proper analysis of the positive points and constraints on the component, it can be safely

concluded that the product is a highly efficient GUI based component. This component can be easily

being plugged in many other systems.

Also the component is highly user friendly. Generally the search and updating in stores are done by non-

technical people. So it is in the best interest of the organization to use such software which their

employees can handle easily. This software comes with just that solution. Being mostly GUI based, this

component can be used very easily. With very little training, users can learn the usage of the product.

Also the search results are presented in numerous forms like report format, graphical format etc which

makes it versatile. Again the GUI based system is certainly more eye-catching and attractive. Nowadays

most of the companies are going global .So their business has also become distributed and diverse.

Lastly I would like to thank all the Staff members of TECHNO CAMPUS for cooperating me during this

training.
