Client Server Messenger using Java

Project Objective

The main objective for building a Client Server Messenger is to provide an advanced communication platform so that multiple people can communicate with each other at the same time. All you need is just an internet connection. You can connect to your group of friends wherever internet connectivity is there. Some of the best examples are Yahoo Messenger, which is used on large scale for chatting purposes.

Client Server Messenger Data flow Diagram

Existing System

When internet was not there, people were not able to communicate as a group. Text messages were the most common mechanism but it did not provide the facility of multiple communications. There are many occasions when communication has to happen in a group only like an official offline meeting or a fun conversation among a group of friends. Moreover, the mechanism of text messages was not cost effective and was relatively slow.

Proposed System

Proposed system although provides multiple conversations which have made the life of so many people easier and interesting. People are more than happy to get such a facility. The Client Server Messenger is a socket application which is multi-threaded in nature, it means multiple users can access the single server application. This is best used in professional environments. This system is very fast and the communication happens very smoothly.

Number of Modules

Sign up- For using the instant messenger, each user must have an account on it. This is the very first step. The user will have to provide all necessary details like name, age, picture, date of birth etc., along with the most important details, username and password. If all the details are correct, the user is successfully registered.

Login –Every time the user wants to access the instant messenger, he will have to provide valid login id and password. Through this login id and password, users will be redirected to their own home page.

Users or groups – This module will have a list of users or groups which a user can add. Before beginning the chatting with one or more users, it is important to add the particular user. In this list, it will be visible that a user is online or offline.

Chat window– In this module, the conversations would happen and all the users in the group will be able to view the conversation and participate in it.

Settings– In this module, the user can modify his profile details like picture, password and other privacy settings.

Online Examination System project in Java

Project Objective

The main purpose of this project is to the development of an online exam system for the ease of students so that they can attempt the exam by sitting at home and they do not need to travel to distant places for giving various exams. This application will also contribute towards e-learning.

Existing System

In the existing system, the examination system is not online. The examination is on paper and the students have to reach the location physically for attempting the exam. Other examination activities like maintaining the list of students, keeping the record of which student has already attempted the exam, calculating marks and deciding scores for students are very tedious and time taking. They are also subject to mistakes and errors as the whole process is manual.

Proposed System

In the proposed system, the examination activities are conducted online. The whole examination process is automated, starting from preparing the question papers of various subjects by the teachers till the calculation of results of students. The life of both teachers and students has become very easy by the introduction of this system. It also offers security as each teacher or student has a secure username and password for accessing the system. The score of a student or a question paper cannot be leaked. The results produced are unbiased as they are computed by the system.

Number of Modules

The application consists of following modules:-

User

Firstly, a fresh student has to register on the application. After registration, he can attempt for an exam. He will be presented with the instructions of exam and then he has to choose the subject whose exam he wants to attempt. After subject selection, the student will get the question paper of the particular subject. He can give the exam in the limited time. Once he finishes the test, he gets the scores immediately with the feedback.

Administrator

The administrator basically performs two important tasks:-

Deciding the subjects of examination.
Deciding the questions of test.

The Subject of exams can be modified like new subjects can be added and old subjects can be deleted.The Questions of the test can also be modified depending on the requirement and changing syllabus.

Administrator can also delete the student records who have finished the test.

Power Billing System project in Java

August 22, 2015 by ProjectsGeek 4 Comments

Power Billing System project in Java

Project Objective

The objective of this application is the development of Electronic Billing System. It is a web-based application which aids the clients and staff members of A.P.S.E.B for dealing with transactions over the internet

With the help of this application, the Customers will be able to file a complaint or manage new connections by just signing in into the system and easily perform the transactions whenever they are online.

Moreover, this product will also provide a stable solution for single tier issues.

Existing System

The main issue in the present system is outdated database technology. In the existing system, the database was maintained using files and that too manually. This is a very slow and tedious process. It also leads to a lot of errors. Modification of data is a big pain. There is high risk of losing data in such management system. So, one has to compromise with the quality, security and durability of data.

Proposed System

The proposed system offers a lot of advantages over existing system. It isbuilt onclient-server architecture and its implementation is done using java technology along with Apache Tomcat server. With this new system, it is very easy for customers to deal with transactions

For starting the application, a user has to enter user name and password for authentication. This system won’t be allowed to access if unauthorized user tries to access it, thereby providing high security.

Power Billing System Snapshots

Number of Modules

Login: -To make a secure system, each customer will have a valid login id and password. Through this login id and password, users will be redirected to their own page with the help of servlet where validation and verification process takes place.

Revenue Collection: -After signing in the application, the customer can perform the revenue collection easily and securely.

Billing and Accounting: – Initially, this was done manually. Now with the help of this module, the accounting data will be quiet less erroneous and inconsistent.

Reports: -This application allows the customer to generate reports which can easily represent the data in a user-friendly format.

Journal details: -The customer can access the journal details comfortably using this application. Even details containing bulk data are available in much lesser time.

Inventory Management System Java Project

August 15, 2015 by ProjectsGeek Leave a Comment

Inventory management system Java Project

Project Objective

The main aim of Inventory management system is to fasten the business processes of a company.Every organization keeps record of the raw materials which it uses and puts ample effort in the optimum resource utilization. If a company chooses to handle all these business operations and keeping track of the usage of resources in a manual way, then it can never progress at a fast pace.

Existing System

In the existing system, the inventory management is handled manually, which is highly tedious. Some of the important business operations are estimating the requirement of new raw material, dealing in the production of Purchase order, purchase invoice, sales invoice and debit note. All these operations are performed by a team of skilled members which are prompt in financial calculations and have a sharp memory. The operations are handled in an effective way, but the process is time taking and subjected to human errors.

Proposed System

In the proposed system, all the business operations will be automated. Some of the features which the new system will provide are Auto generation of Daily Demand report, Auto generation of Purchase Order of various raw materials. As everything is auto generated, the production delays are avoided. It makes the system more secure as only authenticated users can access the system. Also, there are privileges in which we can authorize a particular user for accessing system or particular modules of the application.

Application Snapshots

Number of modules

The following modules are covered under this application:-

Manager operations

The manager interacts with the system once he gets authenticated. In this basically, the inventory information residing at various stores is gathered.

The manager also has the provision of viewing the information that he gets from the sales devices through the HELP module available in the application.

Automatic calculation of data

This module is basically used for the calculation of inventory information stores at all the respective stores. The calculation is completely automatic and not manual.

Security module

Security module is used for authenticating the manager, so that only the legal person will have the access to the system.

Help module

This module is for aiding the manager in viewing the updates of inventory information that when and where it is getting updated.

Software Requirements

Copying Files using Java Code

August 9, 2015 by ProjectsGeek Leave a Comment

Copying Files using Java Code

In this Copying Files using Java application we will learn how to copy file using java code. I have used swings for creating a sample application which has progress bar to tell the progress of copying process. We are using simple java input stream and output stream to copy the file from one location to other location. You have to specify source location which is the file that user is copying. Then he/she has to specify destination location for the copied file, if both the locations are valid file will be copied.

Steps for copying File

Enter source location.
Enter Destination location.
Click the button. If both the locations are valid file will be copied.

Store Management System Project in Java

August 7, 2015 by ProjectsGeek Leave a Comment

Store Management System Project in Java

Project Objective

The main aim of Stores Management System is the automation of all processes for which stores are used like, maintenance and operation works, capital works etc. This automation will almost eliminate the need of clerical staff which works in the technical and account domains in the store. The modern software will be quite efficient in performing the processes and will be proved cost-effective. Also, it will eliminate human errors.

Existing System

In the existing system, open source technologies are used for carrying out the activities of Stores Management System.It is developed using the older platform of windows, i.e., WINDOWS 2000 PROFESSIONAL. It used ‘POSTGRESQL’ as a database platform. In fact, open source technologies are used in all the branches of the power distribution company.Graphical User Interface(GUI) mode is used for effective interaction with the users.

Proposed System

In this project, we will create a web based system which would facilitate a manufacturing firm to create a schedule of all its important operations on a daily basis. The details of the updates about the sales will be provided by its dealers. Once a dealer will enter the sales updates of items on the website for the previous week, along with the next delivery orders, the schedule for the production in upcoming week will be automatically generated. On inputting the correct product requirements and quoting their respective rates, the system will produce the report of all raw materials required. After quoting the rates, the order will be automatically placed and that too on expected delivery schedules

Store Management System Snapshots

Store Management System Modules

This project mainly deals with two modules- reports module and material issues module.

Material issues module– It deals with the application’s specific functionalities. Two main material issues are –issues aroused when the work is allocated according to field requisitions and issues which are related to inter-store works. For both these operations, the gate passes will have to be issued.

Reports module-In this, we basically deal with the Reports that will be generated by the application. Reports are the actual result of a particular process and are basically generated on a monthly basis. The reports which are basically included in the module are SIB Report, SRB report, Issues report of respective sessions, stores abstract, Ledger reports, details of work orders and stock reports.
