Hi,

I am going through below link
http://www.avajava.com/tutorials/lessons/what-is-a-javabean.html

I wonder why java bean needs to implement the serializable interface.

Are there are scenarios where there is no need for java bean to save object to Database or file system so that we do not need to implement serializable interface.(any sample example for that scenario).

In this link they said 'Refrigerator'. I did not get in what context author mentioned that.

please advise
Any links resources ideas highly appreciated. Thanks in advance

You do not need to implement the Serializable interface, unless you need to serialise the data, i.e. you need to pass the bean remotely to another JVM or you need to save its state on the disk.

No, they are the scenarios for "I need to serialise data".

why do we need to pass bean remotely to another JVM

If you are making a remote method call for example. If someone has implemented a remote application and you need access to it. There are several scenarios where this could be useful.
