I have an error in my conversionApplication on the line that states myConverter.convertToEuros(dollarAmt). The red dotted line in under convertToEurros. It tlls me it can not find symbol. What did I forget?
package conversionapplication;
/**

*/
public class EuroConverter
{
// Instance variables (characteristics)
private double conversionRate;
public EuroConverter (double initialRate)
{
}
/**
* @param conversionRate the conversionRate to set
*/
public void setConversionRate(double conversionRate)
{
this.conversionRate = conversionRate;
}
public double convertToEurors(double dollars)
{
double convertToEurrors = 0.00;
double dollarAmount = 0.00;
return 0.00;
}
/**
* converts a dollar amount to Euros
* @param dollars
* @return the conversionRate
*/
public double getConversionRate()
{
double convertedValue = 0.00;
return conversionRate;
}
}
package conversionapplication;
import java.util.Scanner;
/**Currency Converter Application

public class ConversionApplication {
/**

public static void main(String[] args)
{

double convRate;
double dollarAmt = -1;
double euroAmt;
EuroConverter myConverter;
Scanner input = new Scanner(System.in);
// Get user input for conversion rate and construct EroConverter
System.out.print( "Please enter conversion rate (x.xx): ");
convRate = input.nextDouble();
while (convRate <= 0)
{
System.out.print( "Rate cannot be less than zero. Try again: ");
convRate = input.nextDouble();
}
myConverter = new EuroConverter(convRate);
while (dollarAmt != 0)
{
System.out.print( "\nPlease enter the dollar amount to convert or 0 to quit: ");
dollarAmt = input.nextDouble();
if (dollarAmt != 0)
{
// error trap
while (dollarAmt < 0)
{
System.out.print( "Dollar amount cannot be negative: ");
dollarAmt = input.nextDouble();
}
//
myConverter.convertToEuros(dollarAmt);
// displays the converted value in Euros
System.out.printf( "The equivalent value is %.2f Euros.");
}
}
System.out.println("Thank you for using our Euro converter.");
}

You have a typo - it should be convertToEuros
Sorry for offtopic, but it looks like Freudian misprint: Eurors - Errors. Must have debugged the program for a long time :-)

Post your code inbetween the code tags next time. Like this: [*code] code here [*/code]. The actual tags don't have the asterisks in them (*).

Should be
public EuroConverter (double initialRate)
{
conversionRate = initialRate;
}
You also need to return conversionRate in your getter and do something in the convertToEuros method (or it will return 0)

Why is your dollar amount .29? Your dollars is still 0. You never pulled your parameter out and mutated it.

you're always returning 0.00 in the conversion process.
