Serialization Syntax

FileOutputStream filOut = new FileOutputStream("gamestate.ser"); ObjectOutputStream out = new ObjectOutputStream(filOut); out.writeObject(gst); out.close(); filOut.close();

FileInputStream filIn = new FileInputStream("gamestate.ser"); ObjectInputStream ois = new

ObjectInputStream(filIn); gst= (GameState) ois.readObject(); ois.close(); filIn.close();
