Re: [問題] Selection Sorting的問題

Don't fed up.
Are you using IDE to compile and running your code?
If that so, it could probably your IDE problem
on caching to the old version class file.

I have had facing this problem before.
The solution is delete the destination class file
where your source compile to and recompile it again.

Good luck :)
