The elements returned by the directory stream's iterator are of type Path, each one representing an entry in the directory. The Path objects are obtained as if by resolving the name of the directory entry against dir. When not using the try-with-resources construct, then directory stream's close method should be invoked after iteration is completed so as to free any resources held for the open directory. When an implementation supports operations on entries in the directory that execute in a race-free manner then the returned directory stream is a SecureDirectoryStream.

The default is large enough for most purposes. If you want to write some content into a file in java using BufferedWriter, use below code as template and reuse it the way you like.

1) Using BufferedWriter without try-with-resources (Before Java 7). Java example code using BufferedWriter and BufferedOutputStream classes to write content to the end of the file.
