For serializable objects, sufficient information is kept to restore those objects even if a different (but compatible) version of the implementation of the class is present. The Serializable interface is defined to identify classes which implement the serializable protocol: package java.io; public interface Serializable {};Java serialization is the process of converting an object into a stream of bytes so we can do stuff like store it on disk or send it over the network.

Java - 직렬화 예제 (Serialization, Deserialization, Serializable) 직렬화, Serialization은 네트워크 또는 파일로 자바 객체를 전달하기 위하여 byte stream으로 변환하는 것을 말합니다. 즉, Serialization (직렬화)는 Object를 bytes로, Deserialization (역직렬화)는 bytes를 Object로 변환합니다.

2. This is, basically, impossible. If your class has a field of type Object, or List, or Set, or Collection, or any other non-serializable interface, you won't be able to determine if an instance of the class is serializable.
