Skips over and discards <code>n</code> bytes of data from this input
stream. The <code>skip</code> method may, for a variety of reasons, end
up skipping over some smaller number of bytes, possibly <code>0</code>.
This may result from any of a number of conditions; reaching end of file
before <code>n</code> bytes have been skipped is only one possibility.
The actual number of bytes skipped is returned. If {@code n} is
negative, the {@code skip} method for class {@code InputStream} always
returns 0, and no bytes are skipped. Subclasses may handle the negative
value differently.
<p> The <code>skip</code> method of this class creates a
byte array and then repeatedly reads into it until <code>n</code> bytes
have been read or the end of the stream has been reached. Subclasses are
encouraged to provide a more efficient implementation of this method.
For instance, the implementation may depend on the ability to seek.
@param n the number of bytes to be skipped.
@return the actual number of bytes skipped.
@exception IOException if the stream does not support seek,
or if some other I/O error occurs.
