Reading contents of directory(only files and not directories within directory) in java

If we want to print only files and not the directory we can do something like below

We make a filter that checks if a path is a regular file i.e it is not a directory.

    DirectoryStream.Filter<Path> filter =
          new DirectoryStream.Filter<Path>() {
                 public boolean accept(Path path) throws IOException {
                     return (Files.isRegularFile(path));
                 }
           };

     //we can  also create the above filter  using a lambda expression like below
    // DirectoryStream.Filter<Path> filter = p->Files.isRegularFile(p);
We then create a path of the directory in which we want to read all the contents i.e only files and not directories 
Path directory =  FileSystems.getDefault().getPath("FilesTree\\Dir2");
Then pass the above filter to the method newDirectoryStream and it will print only files and not the directory by passing the filer created above as second argument 

  try(DirectoryStream<Path> contents = Files.newDirectoryStream(directory,filter)){
        for(Path file:contents){
            System.out.println(file.getFileName());
        }

    } catch (IOException | DirectoryIteratorException e) {
        e.printStackTrace();
    }
