CreditCardAccount: Write a class to represent a credit card. Call it CreditCardAccount. The class details are as follows:

Static Variables

baseRate The minimum interest rate that the card can have. This should be a constant that is hard coded. Use 9%.

lastAccountNumber The last account number assigned to a customer. Account numbers should be assigned sequentially. Start with 5555.

Instance Variables

accountholder The name of the person who owns the card.

accountNumber A unique 7-digit identifier number.

creditScore The account holders credit score.

rate The annual interest rate charged to the card.

balance The current balance on the card.

creditLimit The card holders credit limit.

Methods

Constructor Should only take the account holders name and a credit score. The next account number available should be assigned. The balance will be 0 as nothing has been charged yet. The rate and credit limit will be determined by the credit score. Use the following table to set the rate and credit limit.

Credit Score	Rate	Limit
0-300	baseRate + 12%	$1000
300-500	baseRate + 7%	$3000
500-700	baseRate + 3%	$7000
700+	baseRate	$15000

makePurchase Takes a purchase amount as a parameter and updates the current balance. If the amount + balance > creditLimit, deny the transaction (print a message to that effect, don't change the balance).

makePayment Takes a payment amount as a parameter and updates the current balance. If the payment is greater than the balance, set the balance to zero and print an appropriate message. If the payment is less than 10% of the balance, apply the payment and raise the account holders rate by 1%. If the balance is paid off entirely, raise the creditScore by 10. If the increased creditScore changes where the account holder falls in the above table, change the rate and limit as appropriate.

raiseRate Raises the account holders rate by a given percentage.

raiseLimit Raises the account holders limit by a given dollar amount.

applyInterest Calculates the balance on a monthly basis. Remember that the rate is yearly, so the formula for calculating the balance monthly is balance + (balance * (rate / 12)).

toString Print the account holders name, account number obscured with stars (ex: 1234567 would display as ****567), balance, and limit.
