Read the javadocs for FilenameFilter:

You want it to print all directories and skip files? I would do it
this way:

File f = new File("C\\Windows");
File[] allItems = f.listFiles();
for(File cur : allItems){
   if(cur.isDirectory()){
    System.out.println(cur.toString();
   }
}

The logic in accept( ) is incorrect. You need to check for the full
file, and not just the parent folder. To get the full file name, you
need to join the directory (arg0) and the file (arg1) with the
separator character.

Change the logic to:

if (new File(arg0.getAbsolutePath()+File.separator
+arg1).isDirectory())
     return true;

and it should work.

Let's tidy it up:

public class TestFilters {
public static void main(String[] args) {
File winDir = new File("C:\\Windows");
String[] subDirNames = winDir.list( new FilenameFilter() {  
 // accept dirs only.
 public boolean accept(File dir, String filename) {
{
return new File( dir, filename).isDirectory();
}
});

for (String subDirName: subDirNames)
 {
System.out.println( subDirName);
}
}

The main thing I did was give each variable a clear name as to what it
contained. Without that, programs become needlessly confusing.

The other thing I did was get rid of your "absolute" call.  You only
need that when you want the precise file names.  They are not needed
to determine if a file is a directory.

Further you the file you are testing has two parts  the dir and the
filename.  You need to create a file handle to test that includes both
parts.

I am impressed you mastered the delicate syntax of the inner anonymous
class. You are no dummy, just one who has not yet learned the
importance of naming.
