Well, the
word "locally" is crucial. It means that in your current project the method is not used. You can
test that by commenting it out, and rebuilding the complete project - it should compile fine. But if it's not a private method then it may be used by other code that uses this class. Not sure if that's applicable to your project, but think of a library - all of its public methods are probably not used by the library itself, but they're certainly used by applications that use that library. In that case it wouldn't be safe to remove the method, because it's part of the public API the library exposes.
