Does the program have to be GUI or is it text based?<br><br>I don't remember the formulae offhand but they are rather simply and of the form y = f(x), meaning that for one x value there is one y value. If you can manage to type out the formulae to display in this forum, then you should be able to convert it to java.<br><br>a simple outline:<br><br>public class Conversion<br>{<br> private double input; // the temperature to be converted<br> private double output;// the value of the converted temperature<br> Char boolean fOrC; //used to determine which way to convert, from F to C or C to f. It Should only contain an "f" or "c"<br> public static void main(String args[]) <br>{<br> //get the input from the user and assign it to the appropriate variables<br><br>if(fOrC == 'c')<br> output = cToF(input);<br> else<br> output = fToC(input);<br> <br> System.out.println(output);<br><br>}<br><br> <br>//the methods<br>public double cToF(double input){}<br><br>public double fToC(double input){}<br><br><br>}<br><br>All you have to do is fill in the methods and it should work. I will not complete the code for you because this sounds suspiciously like a homework question, but there should be enough to get you started. <p> fenris<br><a href=mailto:fenris@hotmail.com>fenris@hotmail.com</a><br><a href= > </a><br> I am interested in Mining Software, as well as Genetic Algorithms.
