How do I detect whether the file system is case-sensitive?

Question

I have a List<String> of file names from a folder and a certain file name as String. I want to detect whether the file name is in the list, but need to respect the underlying file system's property of whether it is case-sensitive.

Is there any easy way to do this (other than the "hack" of checking System.getProperty("os.name", "").toLowerCase().indexOf("windows")!=-1)? ;-)

Answer 1

Don't use Strings to represent your files; use java.io.File:

Answer 2

boolean isFileSystemCaseSensitive = !new File( "a" ).equals( new File( "A" ) );
