public class HiddenFileFilter extends AbstractFileFilter implements java.io.Serializable
Files that are hidden.
Example, showing how to print out a list of the current directory's hidden files:

Example, showing how to print out a list of the current directory's visible (i.e. not hidden) files:

System.out.println(files[i]);
