(Savings Account Class) Create class SavingsAccount. Use a static variable annual Inter-estRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBal ance 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 savings-Bal ance. Provide a static method modifyInterestRate that sets the annual InterestRate to a new value. Write a program 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 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.
