错误:摄氏不能解析为变量 [英] Error: celsius cannot be resolved to a variable

问题描述

使用以下代码获取错误:

Getting error with the following code:

import java.util.Scanner;
public class FahrenheitToCelsius{


 public static void main(String[]args){
    convertFToC();
 }

  /*gets input representing fahrenheit and displays celsius equivalent*/
  public static void convertFToC(){
    Scanner scan = new Scanner(System.in);
    System.out.println("Enter Fahrenheit temperature");
    double fahrenheit = scan.nextInt();            
    System.out.println(fahrenheit + " degrees Fahrenheit is " +
      fMethod(celsius) + " degrees Celsius");
  }


  /* calculates and returns the celsius equivalent */
  public static double toCelsius(double fahr){
    int BASE = 32;
    double CONVERSION_FACTOR = 9.0/ 5.0;
    double celsius = ((fahr-BASE)/(CONVERSION_FACTOR));
    return celsius;
  }
}

我得到以下信息:

Error: celsius cannot be resolved to a variable

我需要使用fMethod调用System.out.println中的toCelsius，但是我一直收到此错误.

I need to use fMethod to call the toCelsius in the System.out.println however i keep getting this error.

推荐答案

System.out.println(fahrenheit + " degrees Fahrenheit is " + fMethod(celsius) + " degrees Celsius"); //Step 4

应该阅读

System.out.println(fahrenheit + " degrees Fahrenheit is " + toCelsius(fahrenheit) + " degrees Celsius"); //Step 4
