How to create object as Serializable?

[Kathiresan Chinnasamy]

Hi Friends,

How to make a object as Serializable..
For Example i got an object(Where the class didn't serializable) in main Class ... i have to serializable this object..

Can anyone help me ?

Just make the class implement the interface Serializable:

public class MyClass implements Serializable {
  // ...
}

Note that the interface doesn't have any methods, so you don't need to implement any methods.

Note: If you cannot modify the class, then it's not going to be possible. You can't make any object serializable.

More a beginner's question.

In theory it is easy; you just add "implements Serializable" after the class name. Serializable is a tagging interface (also called a marker interface) which has no methods.

In practice you need to ensure that all its fields are instances of Serializable classes too.
