Java Program that displays the future investment value

Here's a Java program that reads in the investment amount, annual interest rate, and number of years from the user and displays the future investment value:

import java.util.Scanner;
import java.text.DecimalFormat;

public class FutureInvestmentValue {
    public static void main(String[] args) {
        // Taking inputs from user
        Scanner sc = new Scanner(System.in);

        System.out.print("Enter investment amount: ");
        double investmentAmount = sc.nextDouble();

        System.out.print("Enter annual interest rate (as a percentage): ");
        double annualInterestRate = sc.nextDouble();

        System.out.print("Enter number of years: ");
        int numberOfYears = sc.nextInt();

        // Calculating future investment value
        double monthlyInterestRate = annualInterestRate / 12 / 100; // Convert annual interest rate to monthly rate
        double futureValue = investmentAmount * Math.pow(1 + monthlyInterestRate, numberOfYears * 12);

        // Defining DecimalFormat to round off result to 2 decimals
        DecimalFormat twoDForm = new DecimalFormat("#.##");

        // Displaying the result
        System.out.println("Future investment value is
 

In this program:

1. We use a Scanner to read inputs from the user for the investment amount, annual interest rate, and number of years.
2. The future investment value is calculated using the formula FV = P * (1 + r/12)^n, where FV is the future value, P is the investment amount, r is the annual interest rate (converted to a monthly rate), and n is the number of years.
3. We use a DecimalFormat object to round off the result to two decimal places and then display the future investment value.
