Code needs to be in Java
Thanks in advance for the help.
------------------------------------------------
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 12this interest should be added to savingsBalance. Provide a static method modifyInterestRate that sets the annualInterestRate to a new value.
Write a program called SavingsAccountTest 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 monthly balances for both savers. Next, set the annualInterestRate to 5%, calculate the next months interest and print the new balances for both savers.
------------------------------------------------
This code must follow a few rules:
-SavingsAccount is a public class
-annualInterestRate is a private class variable
-savingsBalance is a private instance variable
-calculateMonthlyInterest is a public instance method
-calculateMonthlyInterest is correctly implemented
-modifyInterestRate is a public class method
-modifyInterestRate is correctly implemented
-Test program instantiates two SavingsAccount objects
-Test program sets the annualInterestRate to 4%
-Test program calculates the monthly interest for each of the 12 months and prints the monthly balances for both SavingsAccount instances as a table
-Test program sets the annualInterestRate to 5%
-Test program calculates the monthly interest for the next month's interest and prints the balances for both SavingsAccount instances.
-Test program is in a public class called SavingsAccountTest

Problem 2 Create class Savings Account. Use a static variable annuallnterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savings Balance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly interest by multiplying the savings Balance by annuallnterestRate divided by 12-this interest should be added to savings Balance. Provide a static method modifyinterest Rate that sets the annuallnterestRate to a new value. Write a program called Savings Account Test to test class Savings Account. Instantiate two Savings Account objects, saver 1 and saver 2, with balances of $2000.00 and $3000.00, respectively. Set annuallnterestRate to 4%, then calculate the monthly interest for each of 12 months and print the monthly balances for both savers.
