Our first converter!

In web pages like Hackerrank, Leetcode they set the return statement always as zero and we modified it as we need, so this lesson teach us exactly that.

I am do not resolving the task! :(

Also, the use of the "return" function? How does it differ from the System.out.println function? It does not teach this!

Okay, I am getting stranded in these classes. Why does it get split up in 2 public statis all of a sudden? There doesn't seem to be an explanation given and it's very confusing.

double FT = 1.8 * celsius +32; return FT;

(9.0 / 5) * celsius + 32 & (9 / 5.0) * celsius + 32 不然9/5是int类型

double fahrenheit = (1.8 * celsius) + 32; return fahrenheit;

one must return ' return fahrenheit; NOT 'return 0;' GOOD LUCK

the decimal thing was strange, it reminds me of significant figures rules. the return issue was interesting bc it stuck out to me, but a few tries landed me with 'what should I tell it to return if this method is called' (not sure if that is the correct thinking, but it worked.) A little confused as to declaration of convertCelsiusToFahrenheit as it seems to do that within the creation of the composite type convertCelsiusToFahrenheit right after public static. the compiler didn't seem to like it if I didn't declare convertCelsiusToFahrenheit in the body. What is going on?...celcius seems fine as int..
