To serialize an object means to convert its state to a byte stream so that the byte stream can be reverted back into a copy of the object. A Java object is serializable if its class or any of its superclasses implements either the java.io.Serializable interface or its subinterface, java.io.Externalizable.

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.

Jan 8, 2024 · Serializable is one of the few marker interfaces found in core Java. Marker interfaces are special case interfaces with no methods or constants. Object serialization is the process of converting Java objects into byte streams. We can then transfer these byte streams over the wire or store them in persistent memory.

See full list on baeldung.com If a serializable class does not explicitly declare a serialVersionUID, then the serialization runtime will calculate a default serialVersionUID value for that class based on various aspects of the class, as described in the Java Object Serialization Specification.

The serialization and deserialization …Sep 7, 2009 · Serializable is only a marker interface; casting something to Serializable isn't useful. Because SerializationUtils.clone () requires an argument on type Serializable, and so if your variable is of type List, you'll need to cast it. @Jesper: It's a marker interface that says it's safe to serialize the class. if you serialize the whole list you also have to de-serialize the file into a list when you read it back.

Serialization is the process of converting an object into a sequence of bytes and rebuilding those bytes later into a new object. In other words, Serialization is used to persist an object. 1. Serializable Interface. Java provides automatic serialization, which requires that the object be marked by implementing the java.io.Serializable interface.Apache Commons Lang has SerializationUtils#clone, which performs a deep copy when all classes in the object graph implement the Serializable interface. If the method encounters a class that isn’t serializable, it’ll fail and throw an unchecked SerializationException. Consequently, we need to add the …The best way to do it is to use SerializationUtils from Apache Commons Lang.
