Class HiddenFileFilter

public class HiddenFileFilter
extends AbstractFileFilter
implements Serializable

This filter accepts Files that are hidden.

Example, showing how to print out a list of the current directory's hidden files:

Using Classic IO

 File dir = new File(".");
 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 (i.e. not hidden) files:

 File dir = new File(".");
 String[] files = dir.list(HiddenFileFilter.VISIBLE);
 for (String file : files) {
     System.out.println(file);
 }
 

Using NIO

 final Path dir = Paths.get("");
 final AccumulatorPathVisitor visitor = AccumulatorPathVisitor.withLongCounters(HiddenFileFilter.HIDDEN);
 //
 // Walk one dir
 Files.walkFileTree(dir, Collections.emptySet(), 1, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getFileList());
 //
 visitor.getPathCounters().reset();
 //
 // Walk dir tree
 Files.walkFileTree(dir, visitor);
 System.out.println(visitor.getPathCounters());
 System.out.println(visitor.getDirList());
 System.out.println(visitor.getFileList());
