Question

As a programmer you must be able to follow precise instructions. You will also not always get precise instructions. You must learn to ask questions and make valid deductions of what is expected.

Code the StudentAccount class according to the class diagram


 Methods explanation:

 pay(double): double This method is called when a student pays an amount towards outstanding fees. The balance is reduced by the amount received. The updated balance is returned by the method. 


addFees(double): double This method is called to increase the balance by the amount received as a parameter. The updated balance is returned by the method.

StudentAccount.pdf

 refund(): void This method is called when any monies owned to the student is paid out. This method can only refund a student if the balance is negative. It displays the amount to be refunded and set the balance to zero. (Use Math.abs(double) in your output message). If there is no refund, display an appropriate message.


Test your StudentAccount class by creating objects and calling the methods addFees(), pay() and refund(). Use toString() to display the object’s data after each method called.
