All numeric values are stored in the header information use the formats of the DataInputStream and DataOutputStream classes. All text values, and all fields (which are text only), contain only 8 bit characters, null terminated if less than the maximum length for the field. The character encoding is 8 bit US ASCII.

then I must use DataInputStream and DataOutputStream to access db-1x1.db?
and someone can tell me which class you use to access db-1x1.db?

Hi,
I believe there are several ways to do that. The way I do is that I just use DataInputStream and DataOutputStream for file's header, and RandomAccessFile for reading/writing/updating record(s) in the db file. Hope that helps.
Cheers,
Michael

Getting someone to think and try something out is much more useful than just telling them the answer.
 
It is sorta covered in the JavaRanch Style Guide.
