can anybody tell something about serialisation with examples..

[Amadeus]

Serialization, as it applies to java, refers to the mechanism used to store persistent data objects. Normally, an object created in java lasts only as long as the virtual machine (the java environment) is running...serialization allows for those objects to be stored external to that, albeit in a slightly flattened state.

This, this, and this should provide you with all you need to begin with serialization.
