How to copy an object by value, not by reference [duplicate]

Answer 1

I know this is a little bit too late but it might just help someone.

In my case I already had a method to make the Object from a json Object and make json from the object. with this you can simply create a new instance of the object and use it to restore. For instance in a function parsing a final object

public void update(final Object object){ 
  final Object original = Object.makeFromJSON(object.toJSON()); 
  // the original is not affected by changes made to object 
}
