I get an error message on my code below. How can I fix it? import java. util. Scanner;

public class CelsiusToFahrenheit {

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

double tempF;
double tempC;

System. out. println("Enter temperature in Celsius: ");
tempC = scnr. nextDouble();

System. out. print("Fahrenheit: ");
System. out. println(tempF);
return;
}
}

CelsiusToFahrenheit. java:16: error: variable tempF might not have been initialized
System. out. println(tempF);
