Serilization or Deserilization (Just plane java code)

Serilization
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ObjectOutputStream oout = new ObjectOutputStream(baos);
oout.writeObject(obj);
oout.close();

ps.setBytes(1, baos.toByteArray());

DeSerilization
byte[] buf = rs.getBytes(column);
if (buf != null) {
ObjectInputStream objectIn = new ObjectInputStream(
new ByteArrayInputStream(buf));
Object obj = objectIn.readObject(); //Contains the object
PersonDetails p = (PersonDetails)obj;
System.out.println(p.getName()+"\t"+p.getAge()+"\t"+p.getSex());
