$8\mathrm{.}6($Savings Account Class$)$ 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 calculatemonthly Interest to calculate the

monthly interest by multiplying the savingsBalance by annualinterestRate divided by $12$

$-$this interest should be added to savings$-$Balance. Provide a static method

modifyInterestRate that sets the annualinterestRate to a new value. Write a program

to test class SavingsAccount. Instantiate two savingsAccount objects, saver$1$ and

saver$2,$ with balances of $$2000\mathrm{.}00$ and $$3000\mathrm{.}00,$ respectively. Set annualinterestRate to

$4\%,$ then calculate the monthly interest for each of $12$ months and print the new balances for both

savers. Next, set the annualinterestRate to $5\%,$ calculate the next month's interest and print

the new balances for both savers.
