Can someone help my code. I want to be able to declare variables though user input, i have figured out the code on double, but not string.

My current code is this.
...................................................................................................................
import javax.swing.JOptionPane;

public class test

{

//class header

double celsiusValue = 0.0; //declares celsiusValue as a double variable
double kelvinValue = 0.0; //declares kelvinValue as a double variable
// String madMax;

public test()
{
System.out.println("Servers Calculation");
}
{

//constructor header


String userInput = JOptionPane.showInputDialog("Enter Fahrenheit temperature");


//System.out.println(userInput);


celsiusValue = Double.parseDouble(userInput);

kelvinValue = celsiusValue; //- 273.0;

// madMax = (userInput);


System.out.println(kelvinValue);



//String userInput = JOptionPane.showInputDialog("Enter Word");

// System.out.println(userInput);
}

public static void main (String[] args)

{//main

new test();//instantiation

}
}

..............................................................................................................

And also, how can i get a couple of Option panels on this code, with questions going to a double variable and string variable.

Thanks

Michael.

your userInput variable is the same in stirng and double

i changed the


to


and it worked. pretty ez fix, am i missing something.
