Create a Java file called CompoundInterestYourLastName. Write a method called computeBalance( ) that computes the balance of a bank account with a given initial deposit, annual interest rate, after a given number of years for the investment. Assume interest is compounded yearly.

The formula for determining compound interest (compounded yearly) is:

A=P(1+r) to the power of t

where:

  • A = the future value of the investment/loan, including interest
  • P = the principal investment amount (the initial deposit or loan amount)
  • r = the annual interest rate (decimal)
  • t = the time the money is invested or borrowed for

Create your method to accept three parameters in this order: initial deposit, annual interest rate as a decimal, after a given number of years.

Your method should return a double value of the future value including interest.

In your main method, run the following tests to verify your method is working correctly.

System.out.printf("Your total is $%.2f", computeBalance(10000, .045, 13));

// should return $17721.96

System.out.printf(" Your total is $%.2f", computeBalance(20000, .03, 15));

// should return $31159.35

System.out.printf(" Your total is $%.2f", computeBalance(30000, .01, 20));

// should return $36605.70

Pay close attention to your parameters to make sure they match the test data!

Your methods should have this exact signature line, including the correct spelling, capitalization and parameter types.
