如何修复此 FileNotFoundException (Java)？

Question

How do I fix this error? I've looked everywhere! I usually ask other Runescape Private Server developers to help with this, but no one ever responds to me. This is the error:

Answer 1

When a FileOutputStream throws the FileNotFoundException , it's because the directory doesn't exist.

In your case, that is the C:\\Specdout\\Data\\Animation directory. Create the directory, and FileOutputStream can create file flo.dat .

Note: Could also be security issues.
