  1. POSimple Java present value calculator is not working
    text
    copied!<p>I have not used java before and I am confused as to why a simple present value calculator I wrote is not working. The present value formula returns a super small number for some reason? See if you can spot my error:</p> <pre><code>// Import all utilities import java.text.DecimalFormat; import java.util.*; // Base class public class Project2 { // Main function public static void main(String[] args) { // Define variables double p = 0.0; double f = 0.0; double r = 0.0; double n = 0.0; String another = "Y"; // Create a currency format DecimalFormat dollar = new DecimalFormat("#,###.00"); // Create a new instance of the scanner class Scanner keyboard = new Scanner(System.in); // Loop while another equals "Y" while(another.equals("Y")) { // Get future value System.out.println("Future value: "); f = Double.parseDouble(keyboard.nextLine()); // Get annual interest rate System.out.println("Annual interest rate: "); r = Double.parseDouble(keyboard.nextLine()); // Get Number of years System.out.println("Number of years: "); n = Double.parseDouble(keyboard.nextLine()); // Run method to find present value and display result p = presentValue(f, r, n); System.out.println("Present value: $" + p ); // Ask if user wants to enter another System.out.println("Enter another?(Y/N) "); another = keyboard.nextLine().toUpperCase(); } } public static double presentValue(double f, double r, double n) { // Do math and return result double p = f / Math.pow((1 + r), n); return p; } } </code></pre>
