A1:	There's a different between the bytes in a stream and the bytes represented by the byte class. A byte in Java has a value ranging from–128 to 127, while a byte in a stream has a value from 0 to 255.

A2:	Java software can access relational databases with either Java Database Connectivity (JDBC) or the JDBC-ODBC Bridge. The same techniques are required ...
