Examples of java.io.DataInputStream.skipBytes()

java.io.DataInputStream.skipBytes()
See the general contract of the skipBytes method of DataInput.
Bytes for this operation are read from the contained input stream. @param n the number of bytes to be skipped. @return the actual number of bytes skipped. @exception IOException if the contained input stream does not supportseek, or the stream has been closed and the contained input stream does not support reading after close, or another I/O error occurs.
