Help code in Java 21. Compound InterestWhen a bank account pays compound interest, it pays interest not only on the principal amount thatwas deposited into the account, but also on the interest that has accumulated over time. Suppose youwant to deposit some money into a savings account, and let the account earn compound interest for acertain number of years. The formula for calculating the balance of the account after a specifiednumber of years is:A = P ( 1 + r n ) n tThe terms in the formula are:A is the amount of money in the account after the specified number of years.P is the principal amount that was originally deposited into the account.r is the annual interest rate.n is the number of times per year that the interest is compounded.t is the specified number of years.Write a program that makes the calculation for you. The program should ask the user to input thefollowing:The amount of principal originally deposited into the accountThe annual interest rate paid by the accountThe…
Java Programming 13: AcctNumsIn.txt has been provided and contains a list of at least 15 six-digit account numbers. Implement the ValidateCheckDigits program to read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file (AcctNumsOut.txt), each on its own line.
