Program Plan Intro

Processing a negative payment amount

Program plan:

• Import the required packages.
• Create a class CreditCard to modify the class by ignoring any request to process the negative payment amount.
• Declare required variables.
• The parameterized constructor CreditCard() takes the input parameters of “cust”, “bk”, “acnt”, “lim”, and “initialBal” to initialize the values.
• The parameterized constructor CreditCard() takes the input parameters of “cust”, “bk”, “acnt”, and “lim” to initializes the values.
• The accessor method getCustomer() is to get the customer name.
• The accessor method getBank() is to get the bank name.
• The accessor method getAccount() is to get the account number.
• The accessor method getLimit() is to get the credit limit.
• The accessor method getBalance() is to get the credit balance.
• The method charge() is to update the balance.
• The method makePayment() is to make a payment when amount is not a negative payment.
• The utility method printSummary() is to display the credit card’s information.
• In main() function.
  • Create an instance for CreditCard class.
  • Initialize the value for credit card details by invoking the parameterized constructors using wallet object.
  • Call the charge() method is to update the balance using wallet object for 3 arrays.
  • Loop executes until the wallet[] object.
    • Call the printsummary() method is to display the credit card details.
    • Loop executes until the getBalance() method value is greater than 200. If yes,
      • Call to makePayment() method to make a payment, then display the new balance.
