What is Deserialization in Java?
After a serialized object has been written into a file, it can be read from the file and Deserialized that is, the type information and bytes that represent the object and its data can be used to recreate the object in memory.
Example
import java.io.*;
public class DeserializeDemo {
public static void main(String [] args) {
Employee e = null;
try {
FileInputStream fileIn = new FileInputStream("/tmp/employee.ser");
ObjectInputStream in = new ObjectInputStream(fileIn);
e = (Employee) in.readObject();
in.close();
fileIn.close();
} catch (IOException i) {
i.printStackTrace(); return;
} catch (ClassNotFoundException c) {
System.out.println("Employee class not found");
c.printStackTrace();
return;
}
System.out.println("Deserialized Employee...");
System.out.println("Name: " + e.name);
System.out.println("Address: " + e.address);
System.out.println("SSN: " + e.SSN);
System.out.println("Number: " + e.number);
}
}Output
Deserialized Employee... Name: Reyan Ali Address:Phokka Kuan, Ambehta Peer SSN: 0 Number:101
