Create class savingAccount. Use a shared class variable to store the annualInterestRate for all SavingAccounts. Each object of the class contains a Private instance variable savingBalance indicating the amount the saver currently has on deposit. Provide the find outMonthlyInterest method to find out the monthly interest by multiplying the savingsBalance by the annualInterestRate divided by 12; this interest should be added to savings balance and returned to the method caller. Provide a shared modifyInterestRate that sets the annualInterestRate to a new value. prepare an application to test class SavingsAccount. Instantiate two SavingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4% then find out the monthly interest and display the amounts of interest earned and the new balances for each of the savers. Then set the annualInterestRate to 5% and find out the next month's interest and display the amounts of interest earned and the new balances for each of the savers.
