* Convenience class for writing character files. The constructors of this
* class assume that the default character encoding and the default byte-buffer
* size are acceptable. To specify these values yourself, construct an
* OutputStreamWriter on a FileOutputStream.
*
* <p>Whether or not a file is available or may be created depends upon the
* underlying platform. Some platforms, in particular, allow a file to be
* opened for writing by only one <tt>FileWriter</tt> (or other file-writing
* object) at a time. In such situations the constructors in this class
* will fail if the file involved is already open.
*
* <p><code>FileWriter</code> is meant for writing streams of characters.
* For writing streams of raw bytes, consider using a
* <code>FileOutputStream</code>.
