Get the original file name in java?

Question

In Windows os, I have a file, for example "README" .

Using java, File("readme").exists() will return true

How to get the true file name, something like this:

  new File("readme").getTrueFileName()  //return "README"

Answer 1

Look at File.getCanonicalPath - that returns the "real" filename.

There's also File.getCanonicalFile which returns the same information but as a File object.

(I've just tested this with your exact situation, and it works fine.)
