Thread: Temperature Calculation Code Java

Hello, I am trying to create a java file that will print out the temperature in Fahrenheit. This is my code.

import java.util.Scanner;
 
public class TemperatureConverter 
{
 
	public static void main(String[] args) 
	{
 
		float temperature;
		Scanner in= new Scanner(System.in);
 
 
		System.out.printf("Enter temperature in degrees Celsius:  ");
		temperature = in.nextInt();
 
                //Getting a red X next to this line.
               fahrenheit = temperature * 9/5 +32;
		//Add this line
		System.out.printf(+temperature + " degrees Celsius is " + fahrenheit + " degrees Fahrenheit.");
 
		//System.out.println(temp1 + " degrees celsius is " + fahrenheit + " degrees Fahrenheit.");
	}
 
}

I need to know what I am doing wrong. Using Eclipse as my platform. I have entered comments where I am getting red X's.

The error I get when I run the program.

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
fahrenheit cannot be resolved to a variable
fahrenheit cannot be resolved to a variable

at TemperatureConverter.main(TemperatureConverter.jav a:24)

Welcome to the forum! Please read this topic to learn how to post code in code or highlight tags and other useful info for newcomers. Highlighting your code is not necessary and won't work when in code/highlight tags. Posting the complete error is enough.

Thank you for your direction.

You need to declare Fahrenheit as a variable. (ie float, int, long, byte...etc)

First of all you have to declare Fahrenheit as a variable i.e float, int etc

ECHO . . . echo . . . echo

Just wanted to let you know I solved the problem. Thank you for your help.

Thanks for letting us know.
