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.
