Re: Beginner java question: Serializable

Common uses are...

1) To save session data in order to be able to allow
users to pick up where they left off. They may have
been in the middle of some activity when they logged
off (or if their session timed out) and the app can
then use the serialized info to restore right back to
where they were.

2) To support remote processing. In this case, a
resource may be serialized on one server, then
transmitted and restored on another.

Thanks,
Ivan Hurtado
