[@shankars4281]

Hashmap is not threadsafe. Hashtable is threadsafe. We can use ConcurrebtHashMap if you want it to be threadsafe.

[@priyankamane6936]

Greak work - Telusko Learnings Naveen, I must say you are just too brilliant in explaining most complex concepts in the most easiest way. There are a lot of videos out there but one thing that sets you apart is your way of explaining these concepts with very simple examples! Hats off!! I appreciate the fact that you also tell us the purpose of the concept, how it was used, what were it's limitations in that version of JAVA, what were the solutions they came up with in the preceding versions of JAVA. Its a full package! Keep up the good work! Super liked this channel and I am looking forward to learn many more aspects of JAVA.

You're the only Indian guy I am subscribed to. I am an American coder. You're an excellent teacher.

[@grenadier2006]

Something is profoundly wrong with this comment. Why is it even important that he is Indian? Is your endorsement somehow more valuable because you are an American coder, or you giving your blessings to people from the outside Western World? Thank you sir.

So I'm here spending many hours looking for the perfect youtube video, just to realise that none of this is actually new to me. I just didn't know what any of it was called, but I already frequently used these things in my code. This is why theory is also very important.
