Java Serialization

Java Serialization: Can Static Values Be Serialized?

In Java, static values cannot be serialized directly. Serialization is the process of converting an object into a byte stream to store it in a file or send it over a network. Static variables are associated with the class rather than with any specific instance of the class, so they are not part of the object's state that can be serialized.
