How Does Java Handle Serialization and Deserialization?
Serialization converts objects to byte streams for storage or transmission.
Deserialization
Deserialization reconstructs objects from byte streams.
Example Code
import java.io.*;
class Person implements Serializable {
String name;
int age;
Person(String name, int age) {
this.name = name;
this.age = age;
}
}
// Serialization
FileOutputStream fileOut = new FileOutputStream("person.ser");
ObjectOutputStream out = new ObjectOutputStream(fileOut);
out.writeObject(new Person("John Doe", 30));
out.close();
fileOut.close();
// Deserialization
FileInputStream fileIn = new FileInputStream("person.ser");
ObjectInputStream in = new ObjectInputStream(fileIn);
Person p = (Person) in.readObject();
in.close();
fileIn.close();
This example demonstrates Java’s serialization and deserialization process.
