For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Serialization in Java - all layers required!

If you want to subject a delicate piece of equipment to an extreme of temperture for a prolonged period, it's no good just putting it in a box, even if that box CAN withstand the temperature extreme. No - you need to have piece of temperature tolerant equipment AND a tempertaure tolerant box if you're going to subject the combination to the extremes.

And so it is when you have a serialiazable object in Java. Not only must you declare that your class implements selializable but you must also ensure that any objects that it contains are also serializable.

If you can selialize an object, it means that you can save it to a file or a database of transmit it via a network, and you'll be able to reconstruct the object later on / at the other end - literally, you're turning the object into a serial stream of bytes.
