3. The leaf is a member method of the path class that returns the end of a directory string, possibly a directory name or a filename. The path class defines a number of similar member functions.
4. The entire method uses the depth first recursive algorithm to search.
Attention:
When you construct a path object with a directory string, filesystem defaults to the UNIX style, and if you are constructing a Windows-style catalog string on a Windows platform, note that the

Try not to use relative paths to the current user directory compared to System.getproperty ("User.dir"), which can be seen in a variety of results. (6) New File (""). GetAbsolutePath () is also available. Note: If there are spaces in these paths, and the spaces are replaced by%20, you can use Path = Java.net.URLDecoder.decode (
