Returns an array of strings naming the files and directories in the directory denoted by this abstract pathname.

Usage

From source file:morphy.utils.FileUtils.java

/**
 * Deletes all files and subdirectories under "dir".
 * //from   w  w  w  . j ava  2  s.  c o  m
 * @param dir
 *            Directory to be deleted
 * @return boolean Returns "true" if all deletions were successful. If a
 *         deletion fails, the method stops attempting to delete and returns
 *         "false".
 */
