    Default Farenheit 2 Celcius Converter output box problem (First Post)

    Hi all,

    I am working on a project for class and I've been tinkering with my code, but I can't seem to solve my error. I am not asking for someone to do my code, but I'm just hoping for a little nudge in the right direction. Any help would be appreciated. I have a couple of hours to knock this out.

    The assignment reads: Develop a Java program (F2C.java) for converting a temperature from the Fahrenheit to the Celsius scale. The program will read the temperature graphically using an input dialog box (JOptionPane.showInputDialog) and will show also the result graphically on a message dialog box (JOptionPane.showMessageDialog).

    I can get my input box to show, but I am unable to get to the output box

    What I have came up with:

    /*

    */


    import javax.swing.JOptionPane;

    public class F2C {
    public static void main(String[] args) {
    // Enter Farenheit
    String Fahrenheit = JOptionPane.showInputDialog(
    "Enter temperature in Fahrenheit:");

    //Process
    temperature = (temperature-32) * (5f/9);


    // Display results
    String output = "nTemperature in Celcius" + String.format("%.2f",temperature);
    JOptionPane.showMessageDialog(null, output);
    }
    }

    I am still a novice myself but I cleaned up what you had a little:

    */
    package temperature;

    import javax.swing.JOptionPane;

    public class F2C {
    public static void main(String[] args) {
    double temperature;
    // Enter Farenheit
    temperature = Double.parseDouble(JOptionPane.showInputDialog(
    "Enter temperature in Fahrenheit:"));

    // Process
    temperature = (temperature-32) * (5.0/9);


    // Display results
    String output = ("Temperature in Celcius is " + temperature);
    JOptionPane.showMessageDialog(null, output);
    }
    }

    madgame618, thanks for helping other users,but don't post ready made code. You know, teach how to fish instead of handing out fish.
    And use code tags when posting code.
