    Unhappy write java program using table that stores celsius and farenheit values that are equal to one another using a loop. use C 0-20

    write java program using table that stores celsius and farenheit values that are equal to one another using a loop. use C 0-20 and convert to farenheit.

    I have to use doubles for Celsius and Fahrenheit and in the formula.
    I get a runtime error with the following displayed:

    I will display a table of temperatures in their Celsius and Farenheit equivalents.
    celsius farenheit
    --------------------

    /* This is my fifth homework */

    import java.util.*;
    import java.lang.*;
    import java.io.*;

    class TemperatureConversion
    {
    public static void main (String[] args) throws java.lang.Exception
    {
    double celsius; // Temperature in degrees Celsius minimum
    double farenheit; // Temperature in degrees Fahrenheit

    System.out.println("I will display a table of temperatures " +
    "in their Celsius and Farenheit equivalents.");

    //Display the degree equivalency headings.
    System.out.println("celsius\t\tfarenheit");
    System.out.println("--------------------");

    //Display the temperatures.
    for (celsius = 0; celsius <= 20; celsius++)
    {
    //Convert to Farenheit
    farenheit = celsius*(9/5)+32;

    //Display degrees in two equivalencies.
    System.out.printf("%d\t\t%.1f\n", celsius, farenheit);
    }
    }
    }

    Please edit your post and wrap your code with code tags:
    [code=java]
    YOUR CODE GOES HERE
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    Look at the docs for java.util.Formatter:

    "Floating Point - may be applied to Java floating-point types: float, Float, double, Double, and BigDecimal"

    Now look at your formatter and see which conversion character you are using for both argument -- which are both doubles.

    BTW, don't use printf. Get in the habit of using String.format() directly.

    Also, "(9 / 5) + 32" will not result in a double literal. I'd create a class constant to use here:

    final double F_SCALE = (9d / 5d) + 32d;

    See: http://docs.oracle.com/javase/tutori...datatypes.html
