I have started loving this series. Always wait for the next one, now Waiting for the 8th, 9th and the List goes on :p. I am getting back into pace because of these and never thought Collections would be so much of interesting practical thinking.
Please keep adding items to the ArrayList<Naveen AutomationLabs> collections = new ArrayList<Naveen :)

Thanks a lot Naveen. :)

The equals method that you are using, is it overridden in arraylist class or is it of object class.
If it is object class equals then it will compare memory addresses.
Plz reslove this query 🙏
