Making A Tempature Conversion Prgram

[Ste]

I have an assignment for programming 1, and the instructions are to make a program where the user can input any number in degrees celsius, and have the program convert it into fahrenheit.

 

So far this is all I have and i don't know where to go from there.

 

/*

*/

import javax.swing.JOptionPane;

public class TrivialApplication {

 

public static void main(String args[]) {

 

String firstNumber= JOptionPane.show.InputDialog("Enter a tempature in Degrees Celeius to convert into Degrees Fahrenheit");

 

 

}

}

 

 

any ideas?

[Muddy]

find the formula for teh conversion its just multiplying and dividing

[red930]

the equation is F= (9/5)xCelsius+32

[Ste]

yes the formula is

 

Fahrenheit=(9/5) * Celsius (the input from user) + 32

 

heres my progress.

public class TrivialApplication {

 

public static void main(String args[]) {

 

String firstNumber= JOptionPane.show.InputDialog("Enter a tempature in Degrees Celeius to convert into Degrees Fahrenheit");

 

int celsius= Integer.parseInt( firstNumber );

int num1= 9;

int num2= 5;

int num3= 32;

 

 

}

}

yeah it wa one of our 1st java assignments, just parse double that string you took in, once you get that apply the formula to the number you get then i suppose your suposed to print the result correct?

 

EDIT: any reason you stored the formula stuff in variables? why not jsut hard code the formula...it wont change.

 

oh and use parseDouble() instead bc if not and you work with it you will loose the percision. you are goign to want the values to a Decimal now arent you .

Uhhhh um hard code?

[cchalogamer]

as in:

 

double result = ((9/5) * celsius) + 32;

 

granted more ( ) than u need but i tend to do that

 

EDIT:

 

ok i hope u understand that bc MY AP comp. Sci. class is about to start. im actually in there...well here....now.

Im so lost.

[cchalogamer]

crap your still lost lol

 

 

ok add

 

double result = ((9/5) * celsius) + 32;

System.out.println("In Deg. F " + result);

 

(actually use the other output stuff you use lol forgot we do everything in console to make it a little less frustrating lol)

 

and it should print out the answer... you dont nees to code variables for all the numbers you use in a formula. it's a waste of time and effort.

 

EDIT: Well i hope that helps you, just finished our quiz. If you think your lost now just wait until you get to Classes/Objects/static arrays/ArrayLists/stacks torture i tell you

Well, it would be that easy except I have to understand it, i have tommorows class period to finish it. though.

Someone asked about this same problem using VB a while back. Search the Programmers Corner forum for it and see if there is anything in there that helps you.
