Question

Hello,

I have mini program that I should to write on java, but actually I couldn't figure out how I should to start.

here is the question:

- Write a console application called FormattedDouble that prompts the user for a double value, reads the user's input with a Scanner object, and prints that value back to the console, formatted to two decimal places using a DecimalFormat object. The prompt should be clear about what the user is expected to enter and the output should also be clearly labeled.

Thanks

Explanation / Answer

programme can be as

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

namespace MortgageCalculator

{

public class MortgageCalculator

{

public static void Main(string[] args)

{

// declare variables

double principle = 0;

double years = 0;

double interest = 0;

string principleInput, yearsInput, interestInput;

// User input for Principle amount in dollars

Console.Write("Enter the loan amount, in dollars(0000.00): ");

principleInput = Console.ReadLine();

principle = double.Parse(principleInput);

//Prompt the user to reenter any illegal input

if (principle < 0)

{

Console.WriteLine("The value for the mortgage cannot be a negative value");

principle = 0;

}

// User input for number of years

Console.Write("Enter the number of years: ");

yearsInput = Console.ReadLine();

years = double.Parse(yearsInput);

//Prompt the user to reenter any illegal input

if (years < 0)

{

Console.WriteLine("Years cannot be a negative value");

years = 0;

}

// User input for interest rate

Console.Write("Enter the interest rate(%): ");

interestInput = Console.ReadLine();

interest = double.Parse(interestInput);

//Prompt the user to reenter any illegal input

if (interest < 0)

{

Console.WriteLine("The value for the interest rate cannot be a negative value");

interest = 0;

}

//Calculate the monthly payment

//ADD IN THE .Net function call Math.pow(x, y) to compute xy (x raised to the y power).

double loanM = (interest / 1200.0);

double numberMonths = years * 12;

double negNumberMonths = 0 - numberMonths;

double monthlyPayment = principle * loanM / (1 - System.Math.Pow((1 + loanM), negNumberMonths));

//double totalPayment = monthlyPayment;

//Output the result of the monthly payment

Console.WriteLine(String.Format("The amount of the monthly payment is: {0}{1:0.00}", "$", monthlyPayment));

Console.WriteLine();

Console.WriteLine("Press the Enter key to end. . .");

Console.Read();

}

}

}
