错误变量可能未初始化

Question

出于某种原因，我得到以下列出的这两个错误。

Error variable fahrenhuit might not have been initialized. 
Error variable kelvin might not have been initialized. 

这是我的代码。

import java.util.*; 
public class TemperatureConversion 
{ 
    public static void main (String [] args) 
    { 
     Scanner sc = new Scanner(System.in); 
     double temperature = sc.nextDouble(); 
     double kelvin = kelvinCalculations(kelvin); 
     double fahrenhuit = fahrenhuitCalculations(fahrenhuit); 
     System.out.println(temperature + "Degrees Celsius is equivalent to " + kelvin + " Kelvin and " + fahrenhuit + " Degrees Fahrenhuit"); 
    } 
    public static double kelvinCalculations(double temperature) 
    { 
     double kelvin = temperature + 273.15; 
     return kelvin; 
    } 
    public static double fahrenhuitCalculations(double temperature) 
    { 
     double fahrenhuit = (((temperature * 9)/5) + 32); 
     return fahrenhuit; 
    } 
} 

此程序从摄氏和fahrenhuit和输入转换/输出必须在主。这就是我认为导致我的大部分问题......也就是在子模块之间传递变量。

调用代码应该是这样的：

double kelvin = kelvinCalculations(temperature); 
double fahrenhuit = fahrenhuitCalculations(temperature);
