Serializable is a empty interface, why in some cases, class implements it.

Welcome to the Ranch

It instructs the JVM (under certain circumstances) to convert the object to a series of bytes, which can be sent across a network, or recorded in a file.

The other naming of this kind of 'empty' interfaces is marker interface.
The concept of providing metadata this way is old and should be replaced with annotations in new applications.
