Make sure you have appropriate accessor/mutator methods Create another child class to represent Faculty. This class will have faculty rank and length of service as attributes along with an office location. Again, add methods as needed.

Code the StudentAccount class according to the class diagramMethods explanation:pay(double): doubleThis method is called when a student pays an amount towards outstanding fees. The balance isreduced by the amount received. The updated balance is returned by the method.addFees(double): doubleThis method is called to increase the balance by the amount received as a parameter. The updatedbalance is returned by the method.refund(): voidThis method is called when any monies owned to the student is paid out. This method can onlyrefund a student if the balance is negative. It displays the amount to be refunded and set thebalance to zero. (Use Math.abs(double) in your output message). If there is no refund, display anappropriate message.Test your StudentAccount class by creating objects and calling the methods addFees(), pay() andrefund(). Use toString() to display the object’s data after each method called
