Question

My doubt is using Scenario 1 it is possible to achieve serialization . If I extend one abstract class which is serializable by many sub classes means , is this possible to achieve ?. As I tried with Scenario 2.

Serializable will be applicable for all beans or not,Please help me.

my doubt scenario 1 and scenario 2 will be same or different.

//method to send message ::: sendMsgs(SerializableObject)

Scenario 1:

public class EmailMaster implements Serializable 
{
// setters and getters
}

Scenario 2:

public abstract class MessageBean implements Serializable 
{ 
}

//whether EmailMaster and EmailEvent  will become serializable ?

public class EmailMaster extends MessageBean 
{
// setters and getters



public class EmailEvent extends MessageBean 
{
// setters and getters
}

Answer 1

Try

Serializable emailMaster = new EmailMaster();

If it works then EmailMaster is-a Serializable. AFAIK, that definitely should work.
