    This content was COPIED from BrainMass.com - View the original, and get the already-completed solution here!

    Write a program that establishes two savings accounts with saver1 having account number 10002 with an initial balance of $2,000, and saver2 having account 10003 with an initial balance of $3,000. Set a common rate of interest at 5% per year. At the end of each month, update the balance by adding one month's interest to the balance, so that the balance compounds

    Print an output that displays the month number and the account number and the balance for each of the two accounts. Use month 0 to display the initial balances, month 1 to display the balances after the first month's interest, and so on. At the end of the year, display the total balance for both accounts combined, like this:

    Monthly balances for one year with 0.05 annual interest:

    Month Account # Balance Account # Balance
    ----- --------- ------- --------- -------
    0 10002 2000.00 10003 3000.00
    1 10002 2008.33 10003 3012.50
    2 10002 2016.70 10003 3025.05
    3 10002 2025.10 10003 3037.66
    4 10002 2033.54 10003 3050.31
    5 10002 2042.02 10003 3063.02
    6 10002 2050.52 10003 3075.79
    7 10002 2059.07 10003 3088.60
    8 10002 2067.65 10003 3101.47
    9 10002 2076.26 10003 3114.39
    10 10002 2084.91 10003 3127.37
    11 10002 2093.60 10003 3140.40
    12 10002 2102.32 10003 3153.49

    Final balance of both accounts combined: 5255.81

    Use two classes, a SavingsAccount class and a YourNameProg4 as your Driver class.

    In the SavingsAccount class, declare a class variable called annualInterestRate, an instance constant called ACCOUNT_NUMBER, and an instance variable called balance. Provide a two-parameter constructor to initialize the instance constant and instance variable, and provide accessors for the instance constant and instance variable. Provide an addMonthlyInterest method to update the balance, by adding (balance * annualInterestRate / 12) to the current balance.

    Also provide a class method that sets the annual interest rate.

    In the YourNameProg4 Driver class, instantiate the saver1 and saver2 objects. Set the annual interest rate at 0.05. Print the table heading lines. Use a for loop to print the initial account numbers and balances and the account numbers and balances each month after that month's interest has been added. After the last month's printout, compute and display the total of both
