I have two different arraylist of objects 

ArrayList<Buckets> parent;
ArrayList<Buckets> child;

Now I want to initialize all the objects of child with parent's value using

child = new ArrayList<>(parent);

But after this whenever I make any changes in child, the parent arraylist also get updated. How can I make the child arraylist independent. I checked the other answers mostly are using collection but its not working here either. Can anyone kindly help me? thank you

    You will have to copy each element individually. Does Your `Bucket` class define a copy constructor which does *deep-copying*? – TheLostMind Nov 17 '15 at 18:20
  • @VinodMadyalkar no i was copying it using the arraylist constructor – user2924551 Nov 17 '15 at 18:23
  • That would create a *new* `ArrayList` with different references to the same Objects as the Original List. Thus changing the value using this List will also be reflected in the Original List. – TheLostMind Nov 17 '15 at 18:25
