Java Help Please

I need major help with a program I am working on - I can get my Convertor.java to compile w/o a problem -

The problem comes when I do my ConvertorTest.java - I am attaching both programs -

Hello all, I had to write a program to convert from fahr to cent; gallons to liters; and dollars to euros.

I got my converter.java to compile without a problem; here is a copy of the program:

public class Convertor
{
public Convertor(int aFahr, int aGal, int aDollar)
{
int tempf = aFahr;
int gallons = aGal;
int dollars = aDollar;
}
public double convertFahrToCent(int tempf)
{
tempf = tempf - 32;

return tempf;
}
public double convertGalToLiter(int gallons)
{
Liter = (gallons * 3.7854118);

return Liter;
}
public double convertDollarToEuro(int dollars)
{
Euro = (dollars * 0.8135);

return Euro;
}

private double tempf;
private double Liter;
private double Euro;


Now here is my problem program - convertortest.java

What am I doing wrong????

javax.swing.JOptionPane;

public class ConvertorTest
{
public static void main(String[] args)
{
final double Fahr_To_Cent = 5.0 / 9.0;
final double Gallons_To_Liters = 3.7854118;
final double Dollars_To_Euros = 0.8135;

String input1 = JOptionPane.showInputDialog(
"Please enter the Fahrenheit degree:");
int tempf = Integer.parseInt(input1);

String input2 = JOptionPane.showInputDialog(
"Please enter the number of Gallons:");
int gallons = Integer.parseInt(input2);

String input3 = JOptionPane.showInputDialog(
"Please enter the amount of Dollars:");
int dollars = Integer.parseInt(input3);

Convertor FahrToCent = new Convertor(tempf);
Convertor gallonsToLiters = new Convertor(gallons);
Convertor dollarsToEuros = new Convertor(dollars);

System.out.println("Fahrenheit to Centrigrade: " * Fahr_To_Cent.Convertor(tempf));
System.out.println("Gallons to Liters: " * Gallons_To_Liters.Convertor(Liters * gallons));
System.out.println("Dollars to Euros: " * Dollars_To_Euros.Convertor(Euros * dollars));

System.exit(0);
}
}

I think you need to define constructors for your Convertor class, one constructor for each variable type it accepts as input.

(the current code says Convertor should be called with all three variables, aFahr, aGal, aDollar)
