Hello Robert!
Serialization is when you break down an object and write it out somewhere, for example you can write an object to a file and later when you need it again you can collect the entire object from that file. You need to implement the Serializable interface to be able to use this technique.
I don't think that this is part of the
SCJP exam at all. If you look at the objectives set up by Sun, you will see that it is not mentioned there.
