Java object serialization

Here is a quick tutorial on how to quickly serialize (write to desk) and unserialize (read from disk) a java object that implements the java.io.Serializable interface:

FileOutputStream fileOutputStream = new FileOutputStream(OBJECT_DATA);

ObjectOutputStream objectOutputStream = new ObjectOutputStream(fileOutputStream);

objectOutputStream.writeObject(serializableObject);

FileInputStream fileInputStream = new FileInputStream(OBJECT_DATA);

ObjectInputStream objectInputStream = new ObjectInputStream (fileInputStream);

Serializable imageFromDisk = (Serializable) objectInputStream.readObject();
