 *
 * <p>
 * Whether or not a file is available or may be created depends upon the

 * object) at a time.  In such situations the constructors in this class
 * will fail if the file involved is already open.
 *
 * <p>
 * The {@code FileWriter} is meant for writing streams of characters. For writing
 * streams of raw bytes, consider using a {@code FileOutputStream}.
