Need help with a "Compilation error" I'm unable to find my error.

Question

https://code.sololearn.com/ceg1yA3NSsXE/?ref=app
The program is supposed to Print the fibonacci number equivalent to the position inserted. The Scanner works but I receive a compilation error shortly after.

Answer 1

These 2 lines:

int[] fib = {1,1,2,3,5,8,13,21,34,55,89,149,238,387,625,1012, 1637};
String res = String.valueOf(fib[fibPos]);
