Description

This lab will give you practice with creating classes and methods. Your assignment is to implement a class called CreditCardAccount. The UML diagram below specifies the instance variables and methods that are members of the CreditCardAccount class. The diagram also specifies the visibility of each member.

While the implementation of the accessor and mutator methods will be straightforward, two of the methods require some specification.

• addPurchase(double amount): boolean
• This method should increase balance by amount, but ONLY if the resulting balance would not be over the limit.
• The method should return true if the amount could be added and false otherwise
• computeInterest(): void
• This method should compute the amount of interest by multiplying the current balance by the current interestRate
• The amount of interest should then be added to balance without regard to the current limit

Testing

The driver program CreditCardAccountTester.java is supplied for you to test your CreditCardAccount class. If you have implemented CreditCardAccount correctly, you should be able to compile and run CreditCardAccountTester, which will perform various tests on your CreditCardAccount class.

Submission

For this assignment you will need to create a Jar file that contains the source code for CreditCardAccount.java that you edited as part of this assignment. Follow these instructions for creating a Jar file.
The Jar file you submit must be named yourlastname_lab5.jar, where yourlastname is your last name

Submit yourlastname_lab5.jar via the UNC Blackboard System under "Assignments → Lab 5" before the deadline.
