Answer:
//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);
}
}

Sample Output 1:
>> 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

Sample Output 2:
>> Please enter the future value
2000000
>> Please enter the annual interest rate
4
>> Please enter the number of years
