Serialization and serialVerUID

[Murray]

I know that if you're using Serialization, it's best to specify a
serialVersionUID in your class to aid version tracking/maintenance. If your
class has several inner classes, do each of these also need their own
serialVersionUID as well? Or do they simply "inherit" the outer class'
version id?

Thanks,

Murray

If those inner classes are also serialised, then yes. This is the main
reason why inner classes can now have final static members.
