How to shorten file path (get canonical path) in java?

Question

Is there any way in java which can shorten absolute path to directory.

For example:

./data/../system/bin/ => ./system/bin/

Answer 1

Yes, use http://docs.oracle.com/javase/7/docs/api/java/io/File.html#getCanonicalPath().

File file = new File("C:/Users/../Users");
System.out.println(file.getAbsolutePath()); // C:\Users\..\Users
System.out.println(file.getCanonicalPath()); // C:\Users
