Serialization and Deserialization in Java
Serializable is a marker interface (has no data member and method) It is used to "mark" Java classes so that the objects of these classes may get a certain capability The Cloneable and Remote are also marker interfaces It must be implemented by the class whose object you want to persist |
What is serializable in Java IO?
- Java IO: Serializable. That Serializable is a marker interface means that it contains no methods. Therefore, a class implementing Serializable does not have to implement any specific methods. Implementing Serializable thus just tells the Java serialization classes that this class is intended for object serialization.
Does a class implementing serializable have to implement specific methods?
- Therefore, a class implementing Serializable does not have to implement any specific methods. Implementing Serializable thus just tells the Java serialization classes that this class is intended for object serialization. Here is an example of a class that implements the Java Serializable interface:
What happens if a superclass is not serializable?
- If you are a serializable class, but your superclass is NOT serializable, then any instance variables you INHERIT from that superclass will be reset to the values they were given during the original construction of the object. This is because the non- serializable class constructor WILL run!
What is an object serialized to?
- The object is serialized to a stream that carries the data. The stream may also have information about the object's type, such as its version, culture, and assembly name. From that stream, the object can be stored in a database, a file, or memory.
