Answer 1

You would use it for fields you want to exclude from serialization. Serialization only applies to classes where either the class or a class in its class hierarchy implements the interface. For instance, java.lang.Throwable implements java.io.Serializable, so all Errors and Exceptions inherit that marker interface.
