deep copy object

https://stackoverflow.com/a/28195274 - My_Object object2= org.apache.commons.lang.SerializationUtils.clone(object1);

https://stackoverflow.com/a/7596565 - using serialization (did not check, theoretically, should work):

If the class is final or cannot be changed, you need to implement the serializable interface. Convert a class to a stream of bytes:

 ByteArrayOutputStream bos = new ByteArrayOutputStream(); ObjectOutputStream oos = new ObjectOutputStream(bos); oos.writeObject(object); oos.flush(); oos.close(); bos.close(); byte[] byteData = bos.toByteArray(); 

Next, we resume the class object from the byte stream:

 ByteArrayInputStream bais = new ByteArrayInputStream(byteData); (Object) object = (Object) new ObjectInputStream(bais).readObject();

A library for cloning is available here: https://code.google.com/p/cloning/

Deep cloning with this library comes down to two lines of code:

  Cloner cloner = new Cloner(); DeepCloneable clone = cloner.deepClone(this);
