s that are hidden.
Example, showing how to print out a list of the current directory's hidden files:
File dir = new File("."); String[] files = dir.list( HiddenFileFilter.HIDDEN ); for ( int i = 0; i < files.length; i++ ) { System.out.println(files[i]); }
Example, showing how to print out a list of the current directory's visible (i.e. not hidden) files:
File dir = new File("."); String[] files = dir.list( HiddenFileFilter.VISIBLE ); for ( int i = 0; i < files.length; i++ ) { System.out.println(files[i]); }
