Create class SavingsAccount. Use a static variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBalance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savingsBalance by annualInterestRate divided by 12- this interest should be added to savingsBalance. Provide a static method setInterestRate that sets the annualInterestRate to a new value. There should also be a method setSavingsBalance to set the initial savings balance for a new saver or you can do it through a constructor.
