  35  * A file output stream is an output stream for writing data to a
  36  * <code>File</code> or to a <code>FileDescriptor</code>. Whether or not
  37  * a file is available or may be created depends upon the underlying
  38  * platform.  Some platforms, in particular, allow a file to be opened
  39  * for writing by only one {@code FileOutputStream} (or other
  40  * file-writing object) at a time.  In such situations the constructors in
  41  * this class will fail if the file involved is already open.
  42  *
  43  * <p><code>FileOutputStream</code> is meant for writing streams of raw bytes
  44  * such as image data. For writing streams of characters, consider using
  45  * <code>FileWriter</code>.
  46  *
  47  * @apiNote
  48  * To release resources used by this stream {@link #close} should be called
  49  * directly or by try-with-resources. Subclasses are responsible for the cleanup
  50  * of resources acquired by the subclass.
