How has Externalizable changed in recent Java versions?

Externalizable in Java allows developers to control the serialization process by implementing the writeExternal and readExternal methods. Over recent Java versions, there have been improvements in the serialization mechanism, performance optimizations, and the introduction of default serialization methods in some Java classes, enhancing Externalizable's usage and flexibility.

<?php class MyClass implements Externalizable { private String name; private int value; public MyClass() { // Default constructor } public void writeExternal(ObjectOutput out) throws IOException { out.writeUTF(name); out.writeInt(value); } public void readExternal(ObjectInput in) throws IOException, ClassNotFoundException { name = in.readUTF(); value = in.readInt(); } // Getters and setters for name and value } ?>
