Object Persistence in Java

Convert objects to byte streams and back

---

🎯 About

Learn Java Serialization - converting object state to byte stream for storage or transmission, and restoring it back (deserialization).

💡 Concept

┌──────────────┐     Serialize      ┌──────────────┐
│ Java Object  │ ─────────────────► │ Byte Stream  │
│              │ ◄───────────────── │ (File/Network)│
└──────────────┘    Deserialize     └──────────────┘

📚 Topics Covered

• ✅ Serializable interface
• ✅ ObjectOutputStream
• ✅ ObjectInputStream
• ✅ transient keyword
• ✅ serialVersionUID

💻 Example

// Serialization
ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("object.ser"));
oos.writeObject(myObject);

// Deserialization
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("object.ser"));
MyClass obj = (MyClass) ois.readObject();
