+ * 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 {@code FileWriter} (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} is meant for writing streams of characters.
+ * For writing streams of raw bytes, consider using a
+ * {@code FileOutputStream}.
