Serialization in Java
Serialization in Java is a mechanism of converting the state of an object into a byte stream . This byte stream can be persisted into a file, transferred over a network, or stored in a database. The reverse process of recreating an object from the byte stream is known as Deserialization . ✨ Why Serialization? To save the state of an object for later use (Persistence). To send objects between JVMs (Distributed applications, RMI, Messaging). To cache data temporarily. To store objects in databases or files. ⚙️ How Serialization Works Serialization is implemented using the java.io.Serializable interface. This is a marker interface (does not contain methods) that signals the JVM that the class can be serialized. Basic Example: import java.io.*; class Student implements Serializable { int id; String name; Student(int id, String name) { this.id = id; this.name = name; } ...
