File
s that are hidden.
Example, showing how to print out a list of the current directory's hidden files:
Using Classic IO 
File dir = FileUtils.current(); String[] files = dir.list(HiddenFileFilter.HIDDEN); for (String file : files) { System.out.println(file); }
Example, showing how to print out a list of the current directory's visible (not hidden) files:
File dir = FileUtils.current(); String[] files = dir.list(HiddenFileFilter.VISIBLE); for (String file : files) { System.out.println(file); }
Using NIO 
final Path dir = PathUtils.current(); final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(HiddenFileFilter.HIDDEN); // // Walk one directory Files.walkFileTree(dir, Collections.emptySet(), 1, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getFileList()); // visitor.getPathCounters().reset(); // // Walk directory tree Files.walkFileTree(dir, visitor); System.out.println(visitor.getPathCounters()); System.out.println(visitor.getDirList()); System.out.println(visitor.getFileList());
Deprecating Serialization 
Serialization is deprecated and will be removed in 3.0.
