Create A Java File That Will Print Out Temperature In Fahrenheit?

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
