Writing Java Object To Database

it is too easy to write java object to database with the use of following code

import java.io.Serializable;

public class Employee implements Serializable {
    private int Id; 

    private String firstName;

}

Employee object = new Employee();
PreparedStatement pstmt =conn.prepareStatement(SQL_INSERT_QUERY);

pstmt.setString(1, "Employee");
pstmt.setObject(2, object);
pstmt.executeUpdate();

here pstmt.setObject(2, object); statment will write java object to  database as one record record.

implements Serializable is important to serialization of java object to database.
