public class myClass implements Serializable
{
 private int intData ;
 private String stringData ;
 private myEnum enumData ;
 private Collection<someOtherClass> someOtherObjCol ;

 // Other parts

 static final long serialVersionUID = 1L;

}

My understanding is given below, to make myClass objects eligible for
serialization:
- int, String data are serializable by default. So, nothing
additionally needs to be done for them.
- All enum(introduced in Java 1.5) objects are serializable by
default. So, nothing additionally needs to be done for them.
- someOtherClass should implement the Serializable.

So, to make myClass objects serializable, I should just make
someOtherClass objects to be Serializable.
I assume no other changes are required.

Can anybody confirm this?
