bytes of memory. In contrast to the DataInput.skipBytes(int)
method,
this method always skips the desired number of bytes or throws an EOFException

- The number of bytes to skip.IOException
- Thrown, if any I/O related problem occurred such that the input could not
be advanced to the desired position.public int read(byte[] b, int off, int len) throws IOException
