Objectives:

At the end of this activity, you should be able to:

define classes
implement polymorphism and inheritance
instantiate an object array
apply Exception to all input validations
create a Java application for multiple users

Procedure:

Create a NetBeans project for this activity. The project name should be as follows:

o Client (the main class that contains the main method and the implementation of the main menu)

o Credit (the class where attributes and methods are defined)

The class names to be created are the following:

o Client<your_last_name> Ex. ClientBlanco
o Credit<your_last_name> Ex. CreditBlanco

All class names must be suffixed with your last name.
Note that the object to be instantiated in the main method is an object array.
For example: CreditBlanco [ ] cb = new CreditBlanco [100];
Compress the NetBeans project into .rar or .zip format and then upload to the link provided in the LMS.
Only NetBeans project compressed in .rar or .zip format will be accepted.

Java Credit Main Menu
[1] New Credit Account
[2] Credit Inquiry
[3] Purchases
[4] Payment
[5] Close Credit Account
[7] Exit

Program Specifications:

1. New Credit Account

Input the name of the client
Input the annual income and assign the credit limit as follows:

Annual Income	Credit Limit
200,000 and above but not greater than 300,000	30,000
300,000 and above but not greater than 500,000	60,000
500,000 and above	100,000

Generate and display a random four-digit credit account number
Display also the credit limit. The credit limit is the maximum amount of credit
An annual income below 200,000 is not eligible for the credit

2. Credit Inquiry

Input the credit account number and validate
If the credit account number is valid, display the credit account number, credit account
name, credit limit and credit balance.
The credit balance is the outstanding balance or the total amount due.

3. Purchases

Input the credit account number and validate
If the credit account number is valid, input the amount of purchases of not less than Php 1 and not greater than the credit limit and the allowable purchase amount.
Compute and update the credit balance and allowable purchase amount as follows:

Credit balance+=amount of purchases
Interest=3% of credit balance
Credit balance+=interest
Allowable purchase amount = credit limit – credit balance

The allowable purchase amount is the difference between the credit limit and the
credit balance. The credit balance should not exceed the credit limit.

4. Payment

Input the credit account number and validate
If the credit account number is valid, input the amount of payment of not less than Php 1 and not greater than the credit balance
Compute and update the credit balance as follows:

Credit balance – = amount of payment

5. Close Credit Account

Input the credit account number and validate
If the credit account number is valid, confirm if the user wants to close the account.
If confirmed by the user, he should be required to pay all the credit balance before closing the account.
Otherwise, go back to the main menu.
If the account has been closed, the credit account should not exist anymore.

6. Exit

Terminate the Program

7. All input values must be validated and must be required for re-entry of data when invalid.

8. The use of Exception for all input validations is required.
