advantage of serialization over i/o classes

[Ritesh raushan]

what's the problem in i/o classes to save the state of object.what's the advantage of Serialization over i/o classes.

[Jeff Verdegan]

I don't understand the question. Serialization uses I/O classes. Why do you think there's a problem or an advantage or a "one vs. the other" situation?

[Seetharaman Venkatasamy]

serialization performs deep copy by default. if you wish to go with your own then you need to take care all of this.

[Campbell Ritchie]

But serialisation can impose a severe performance overhead on copying objects.
You ought not to think about serialisation versus I/O. Serialisation is one way to make an object suitable for I/O.
