Fahrenheit to Celcius program error

[bosoxfan]

Hello everyone,

I am new to Java Forums and also new to Java programming. I have made a program that allows a user to choose to convert a temperature to either farenheit or celcius and I am getting an error that I cant seem to resolve and was hoping that someone may be able to help me out. The error I am getting is the compiler is stating that i need to declare Farenheit and celcius which I have done in the beginning but yet I am still getting an error. Here is my code for your review:

--------------------------------------------------------------------------

import java.util.Scanner;

public class FtoCtoF
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);

System.out.println ("Welcome to the tempterature converter");
System.out.println ("Please select 1 to convert from Farenheit to Celcius");
System.out.println ("Please select 2 to covert from Celcius to Farenheit");

int inputNum = input.nextInt();
double farenheit;
double celcius;

if (inputNum == 1)
{
System.out.println("Please enter the Farenheit temperature you want to convert to Celcius");
celcius = input.nextDouble();
celcius = (5.0/9) * (farenheit - 32);
System.out.println ("The celcius temperature is:" + celcius);
}

else if (inputNum == 2)
{
System.out.println ("Please enter the Celcius temperature you want to conver to Farenheit");
farenheit = input.nextDouble();
farenheit = (9.0/5) * (celcius + 32);
System.out.println ("The farenheit temperature is:" + farenheit);
}
}
}



Thanks in advance for any help.

Solution:


import java.util.Scanner;

public class FtoCtoF
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);

System.out.println ("Welcome to the tempterature converter");
System.out.println ("Please select 1 to convert from Farenheit to Celcius");
System.out.println ("Please select 2 to covert from Celcius to Farenheit");

int inputNum = input.nextInt();
double farenheit=0.0;
double celcius=0.0;

if (inputNum == 1)
{
System.out.println("Please enter the Farenheit temperature you want to convert to Celcius");
farenheit = input.nextDouble();
celcius = (5.0/9.0) * (farenheit - 32);
System.out.println ("The celcius temperature is:" + celcius);
}

else if (inputNum == 2)
{
System.out.println ("Please enter the Celcius temperature you want to conver to Farenheit");
celcius = input.nextDouble();
farenheit = (9.0/5.0) * (celcius + 32);
System.out.println ("The farenheit temperature is:" + farenheit);
}
}
}

Aseem,

Thank you very much for your help. I figured it was going to be something relatively easy but I spent hours trying to resolve on my own. Now I know next time to come to a place like this and ask for help if my own research turns up nothing!

Thank you again!!! :)
