I have two classes that convert dollars to euros and there is a problem and I need help.

public class CurrencyConversion {

private int moneyD, exRate;

public CurrencyConversion () {  }

public void setDollar(int dollar)
{
	moneyD = dollar;
}
public void setRate(int rate)
{
	exRate = rate;
}
public double getEuro()

{
	return moneyD * exRate;
}

}


Currency Conversion Tester Class:
import java.util.Scanner;
/**

public class CurrencyConverterTester {

	/**
	 * @param args
	 */
public static void main(String[] args) {
		// TODO Auto-generated method stub

Scanner in = new Scanner(System.in);
CurrencyConversion d = new CurrencyConversion();

System.out.println("How many Euros in one dollar: ");

String exRate = in.next();

System.out.println("Enter dollar value (Q to quit): ");

String  moneyD = in.next();

while (!moneyD.equalsIgnoreCase("Q"))
{
	d.setDollar(Integer.parseInt(moneyD));
	System.out.println(moneyD + " dollar = " + d.getEuro() + " Euro" );
	
	System.out.println("Enter dollar value (Q to quit): ");
	moneyD = in.next();
}
System.out.println("Good Bye!!!");	

}

}
