Credit Management System Project in Java

Note:

it doe not contain usage of database

Background:

This mini project helped us a lot. Working in a group made us come up with different idea’s which further helped us to get a better understanding of java and its application’s. This program was mainly created to make the management in canteen easier for the customers as well as the people managing the canteen. Credit management system has the ability to create a food menu items, create desktop applications that will generate orders, calculate the bill by adding the prices of the things ordered and also to keep record of the unpaid bills. In this way it is easy to manage and more beneficial. This management system will not only help the owner of the canteen to prevent any loss but also the customers who run out of low payment.

Why we choose this topic?

The conventional system of Credit Billing is not so effective; Canteen Owners have to note everything on a book. When, the students comes with money, the canteen owner has to turn the thousand pages notebook to find the name of the student, making the work very inefficient to both the worker as well as the customer. Hence, the conventional Credit Management System is uneconomical, high chances of losing data and is a lengthy process overall. In order to solve this lengthy process and loss of data, a window based computerized system is essential. This proposed Credit Management System project overcomes all these drawbacks with the features aforementioned. It is beneficial to both consumers and the canteen owners.

Aim:

Using Object-Oriented Programming Concepts and API Features available in java programming language to create a Mini- Project (credit management system).

Objective:

The main objective of this project is to develop a trusting relationship with the customers so that the business outcomes are achieved and profits are increased. Safeguarding customer risk, settling outstanding balances and improving cash flow are the main objectives of this project. A well-designed system which makes not only the management team’s work easier and more effective (grab more customers) but also the customers (paying and asking credit). A new software system to modernize the Credit management procedure is required. This Credit Management system project would replace the existing traditional type of Credit management system ensuring security, ease and comfort to customers as well as the owners. It meets the current user demands, and new features can be easily integrated into the system in future as per users requirement

Code Explaination:

It contains two packages :
1.Backend(1 class)
2.Default(7 classes)

The backend package stores the details of the customer and verifies it during login process

Code Snippet of backend package: verifiaction Class

package backend;
public class verifiaction 
{
	public static int setId;
	public static int sum;
	static String Pas;
	public static String name="user";
	public static int phone;
	public static String gender;
	public static String Course;
	public boolean verify(int x, String y)
	{	
		String Password = "123";
		int id=123;
		if( x== id && y.equals(Password) || x==setId && y.equals(Pas))
		{
			return true;
		}
		else
		{
			return false;
		}
	}
	public void store(String n, int P,int id,String pa,String gen,String course)
	{
		Pas=pa;
		setId=id;
		name=n;
		phone = P;
		gender =gen;
		 Course = course;
		System.out.println(name+ Pas + setId + phone +gender+course);
	}
	public String name()
	{
		return name;
	}
	public void total(int x, int x1, int x2, int x3, int x4, int x5, int x6, int x7, int x8, int x9, int x10, int x11,
			int x12, int x13, int x14, int x15, int x16, int x17, int x18, int x19)
	{

		x = x*100;
		x1=x1*90;
		x2=x2*30;
		x3=x3*30;
		x4=x4*60;
		sum=(x1+x2+x3+x4+x5);
		x5=x5*50;
		x6=x6*50;
		x7 = x7*40;
		x8=x8*30;
		x9=x9*25;
		sum= sum + (x5+x6+x7+x8+x9+x10);
		x10=x10*30;
		x11=x11*20;
		x12=x12*50;
		x13=x13*60;
		x14=x14*70;
		sum= sum+(x10+x11+x12+x13+x14);
		x15=20*x15;
		x16=3*x16;
		x17=x17*25;
		x18=x18*25;
		x19=x19*35;
		sum=sum+(x15+x16+x17+x18+x19);
	}

}

The default package has 7 classes used for different purposes

Conclusion:

We could run the program successfully and anyone who are access to this project can run and use it without any trouble as it was made a lot easier. The developed system accomplishes all the objectives stated for the need for the change of the system. First the users need to click the signup button whereby they have to register a form so that there won’t be any kind of mistrust and confusion at the end. After filling up the registration form you can login and then click the ‘ask credit’ button and add any number of items to the cart from any of the available food categories by simply clicking the ‘I accept the terms and conditions’ button for the total amount of items you asked for. Once the total amount of money is generated, you have to choose the proceed button wherein you will be asked to choose the canteen from which you are going to purchase things you ordered. Once you have selected the canteen name you have to click the ‘add to credit’ button whereby the credit will be given for one month. For paying the credit, you need to click the ‘back’ button which will be on the top left-side corner and then you can click the ‘paying credit’ button which will show you the total amount of things you purchased, the canteen from which you purchased those things and the date on which those things where purchased. You can even check your details by clicking the ‘check details’ button. Application of all the concepts of GUI made the project possible. It can be an efficient, convenient and fast mode to purchase anything with all the required information. Lastly I would like to thank sir for giving us such an opportunity which helped us to further enhance our knowledge on Java its application in real life.
