Question

Use JGRASP if possible and try to keep it at a beginner level.

Write a Java proof-of-concept program that reads the value of today's dollar, from the user, in Euros. Your program then reads U.S. dollar values and converts each to Euros. Use 0 as a sentinel to terminate the program. Use a do while loop in this program.

Answer 1

import java.util.Scanner;

public class CurrencyConverter {

public static void main(String [] args) {

double USD; // The amount of USD to convert to Euros.

double USDToEuro; // The USD to Euro conversion rate.

boolean done = false;

Scanner value = new Scanner(System.in);

System.out.print("USD to Euro conversion rate: ");   

euroToUSD = value.nextDouble();

while (!done) {

System.out.print("Your USD will you convert to Euros? OR Enter 0 to quit: ");

USD = value.nextDouble();

if (USD == 0) {
done = true;
} else {

System.out.println(USD + " USD is worth " + Convert(USD, USDToEuro) + " Euros";

}

}

}

public static double Convert(double USD, double USDToEuro) {

return USD * USDToEuro;

}

}
