Question about the converter task

Question about the task

Resolved

Hello everyone, i have a question about the converter task. I'd like to know if casting the double type like this is another possible way like writing 9/5.0 public static double convertCelsiusToFahrenheit(int celsius) { //write your code here double TF = (double)9/5 * celsius + 32; return TF; I tried to do it but i already submitted the other answer, so i'm curious to know if this would actually work. Thanks

Here is a very good online IDE compiler, you can always try any program here: https://www.jdoodle.com/online-java-compiler/ (It has dark theme, too.) You can try:

9/5.0 * celsius
9.0/5 * celsius
(double)9/5 * celsius  // it means: 9.0/5 * celsius
1.8 * celsius
(double)(9/5 * celsius) // Java can run this, but it gives not the wished value

That's possible, too (implicite cast - widening primitive conversion).
