Im still getting the last task wrong. Im not sure what I did wrong.

Question about the task

Under discussion

package com.codegym.task.task01.task0130; public class Solution { public static void main(String[] args) { System.out.println(convertCelsiusToFahrenheit(41)); } public static double convertCelsiusToFahrenheit(int celsius) { double TC = 41; double TF = 1.8*TC+32; return TF; } }

The convertCelsiusToFahrenheit(int celsius) method accepts a value in degrees Celsius. The method should convert the temperature and return the value in degrees Fahrenheit.
The Celsius temperature (TC) and the Fahrenheit temperature (TF) are related by the following relationship:
TF = (9 / 5) * TC + 32.

Consider this example:
A value of 41 is passed to the convertCelsiusToFahrenheit method.

Example output:
105.8

Requirements:

The convertCelsiusToFahrenheit(int) method must be public and static.
The convertCelsiusToFahrenheit method must return a double.
The convertCelsiusToFahrenheit method should not display anything.
The convertCelsiusToFahrenheit method must correctly convert degrees Celsius to degrees Fahrenheit and return the result.

package com.codegym.task.task01.task0130; /* Our first converter! */ public class Solution { public static void main(String[] args) { System.out.println(convertCelsiusToFahrenheit(41)); } public static double convertCelsiusToFahrenheit(int celsius) { double TC = 41; double TF = 1.8*TC+32; return TF; } }

you can remove line 14 and just put 'celsius' instead 'TC' in the next line...that is also correct.

Hi Chris, You invoked the method in line 10 with '41'. Now look at line 13 which has ' int Celsius' as its argument. That means ' int Celsius = 41'. The compiler automatically assigns 41 as int Celsius by using that method. Hence, you don't need to assign 41 to Celsius again. I hope this helps you understand why assigning Celsius to TC makes it run properly.

write double TC = celsius; no need to put the value 41 in that declaration...

I dont understand why putting celsius = Double TC makes it works. I dont understand that code line.

variable with value 41 is "int celsius" Get it out of "TC" and enter the "celsius" to the equation

You hard coded 41 into the method. Now if you change the temperature that you want converted (line 10) to anything other that 41 it will output the wrong information. You need to fix this.
