The class uses a file pointer that represents a byte-offset within the file for the next read or write operation. The file pointer is moved implicitly by reading Java 7 SE Lessons or writing and explicitly by calling the seek or skipBytes methods. The current position of the file pointer is returned by the getFilePointer() method.
