Need clarification on serialVersionUID variable in java class.

[Thennam Pandian]

Hi,

Have seen the following member in most of the Serializable classes.

private static final long serialVersionUID = 4374092139857L;

What is the use of this member in the serialization process?
What is the advantage of having this member?

Please SearchFirst, especially in our I/O forum. This question has already been asked many times.
