Examples of java.io.RandomAccessFile.seek()

java.io.RandomAccessFile.seek()
Seeks to the position pos in this RandomAccessFile. All read/write/skip methods sent will be relative to pos. @param pos the desired file pointer position @throws IOException If the stream is already closed or another IOException occurs.
