- * Instances of this class support both reading and writing to a

- * array of bytes stored in the file system. There is a kind of cursor,
- * or index into the implied array, called the <em>file pointer</em>;
- * input operations read bytes starting at the file pointer and advance
- * the file pointer past the bytes read. If the random access file is
- * created in read/write mode, then output operations are also available;
- * output operations write bytes starting at the file pointer and advance
- * the file pointer past the bytes written. Output operations that write
- * past the current end of the implied array cause the array to be
- * extended. The file pointer can be read by the
- * {@code getFilePointer} method and set by the {@code seek}
- * method.
- * <p>
- * It is generally true of all the reading routines in this class that
- * if end-of-file is reached before the desired number of bytes has been
- * read, an {@code EOFException} (which is a kind of
- * {@code IOException}) is thrown. If any byte cannot be read for
- * any reason other than end-of-file, an {@code IOException} other
- * than {@code EOFException} is thrown. In particular, an
- * {@code IOException} may be thrown if the stream has been closed.
