For one class implements serializable

Serializable indicates "serializable"

If there is Class B and it does not have implements serializable. When Class B is started for serialization, the system returns the notserializableexception.

When we want to pass our own classes in different activities, we can use this method:

Intent intent = new intent ();
Bundle bundle = new bundle ();
Bundle. putserializable ("user", user );
Intent. putextras (bundle );

 

This user class must be implements serializable before it can be smoothly compiled by putserializable.
