7. JAVAC vs JAVA for 32/64 bit forums.oracle.comI want to produce Java application for 64 bit architecture.

8. Packing and Unpacking BITS from a SHORT forums.oracle.comThe approach I use to encode the short value involves taking my input byte array and casting each into a short.

The values in the byte-array are assured ... |

13. Why Should I NOT Do This? Warning - A Bit of Code forums.oracle.comHi, one thing about your DAO: you have the finally-block which calls close() on a ResultSet and a PreparedStatement. Apart from rs.close() being called twice, each of those calls may throw an SQLException. So, if rs.close() throws the Exception, statement will never be closed and the Connection will never be released. Similarly if statement.close() throws the Exception: your Connection will not ... |

27. why would one strip the least significant bits when casting? forums.oracle.comThanks (to both respondents.) It makes sense now. One the other end of things is a c++ app that is writing data to the socket I have open. It is probably writing an unsigned short, which I think C++ actually supports, right?

29. Parsing Bit level data formats forums.oracle.comOh, by the way, you may have to be careful about byte ordering. The readInt method of DataInputStream (and other classes that implement DataInput) assume the four bytes of an int are sent in big-endian fashion -- highest to lowest in byte order. Check to see if the bytes are being written in big-endian or in little-endian fashion. |
