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.

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.

 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

Puzzle Game in Java

 

 

 

Project Objective

The main theme behind developing puzzle game using java is to provide a creative and competitive environment for the players who will use this system. The important part of this game, it’s an online web application which can be access from anywhere using its domain name of by assigning IP address. It’s a game where two modules has been provided over a single platform. Here the users have the choice to select the game as per their choice and play at free of cost with full features. Some extensive graphical interface has been used to give excellent picture quality and its optimized code will help users to get processing work faster without any delay.

Existing System

Previously, there was no facility of having online games and if provided, most of them having signup options. But to make easy gaming options, there was no single button sign up options. There was no provisions of changing gaming control and settings to allow players a convenient playing environment. The most among many was the feature of random AI which was not available under existing system. There was no provisions of adding extra gaming section for future reference by the admin to make their website highly demanded in coming future. The point which was not available was decision control by the system. Previously the system was bound to use predefined rules, but the new system will over ride all these difficulties.

Proposed System

In this new gaming environment, no registration and fees required to play the games. Among all, there are two types of games which can be played by the users. They have to options to switch in between these games while playing and the system will keep track of their scores ion particular modules. To make an interesting gaming environment, these two games which will be available are: graphical number puzzle game and another one is disaster strike. We have tried to code smart decision making algorithms to make system more intelligent and can learn the moves from the human beings. At the same time, while playing most of us faces difficulties while handling keys and other controls. To overcome from all these problems, users have been provided freedom, to change the gaming control as per their convenience and change settings to have their controls while playing the games.

It’s the system which allows users to send text messages, enabling voice communication and video communication using this single platform.

Existing System

Existing system does not allow you to establish voice communication using internet by using your desktop or laptop. To have voice communication, you have to use landline telephone services for which you have to invest. The users have to make extra investment during the time of conferencing which includes communication with more than one users. Taking landline telephone services, you need time and there was no medium for global identification system. Using landline telephone services, users cannot able to express their views in terms of smileys. Sometimes during corporate level communication, you also require some sharing medium in emergency cases which was not possible with landline telephone services.

Proposed System

It’s the new VOIP which can be used for individually or by corporate level persons. It’s the communication medium by which users can make calls using internet, can send instant messages to other users and also enables them to have video communication among others. Using this system, it just not only saves time, but also saves travelling expenses. Within this system, some of the features of chatting like sending documents of particular size has been made possible to give all facilities to their users over a single platform.
