Write a program that will calculate the amount of money (Present Value) that you need to deposit into an account today at an annual interest rate of r in order to have a specific amount of money (Future Value) in n years. The formula you will use to calculate the Present Value is the following.
P= F / (1+r)ⁿ

//Import the Scanner class

import java.util.Scanner;

//Class definition

public class FutureValue {

   //main method declaration

   public static void main(String[] args) {

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       //Prompt the user to enter the future value

       System.out.println("Please enter the future value");

       //Store the user input in a variable

       double futurevalue = input.nextDouble();

       //Prompt the user to enter the annual interest rate

       System.out.println("Please enter the annual interest rate");

       //Store the user input in a variable

       double annualrate = input.nextDouble();

       //Promppt the user to enter the number of years

       System.out.println("Please enter the number of years");

       //Store the user input in a variable

       double numberofyears = input.nextDouble();

       //Now use the given formula to calculate t he amount to store now (present value)

       double presentvalue = futurevalue / Math.pow((1 + annualrate), numberofyears);

       //Display the result

       System.out.println("The present value of money should be " + presentvalue);

   }

}

>> Please enter the future value

100000

>> Please enter the annual interest rate

9

>> Please enter the number of years

2

>> The present value of money should be 1000.0

>> Please enter the future value

2000000

>> Please enter the annual interest rate

4

>> Please enter the number of years

3

>> The present value of money should be 16000.0
