After scanning through a ton of implementations this has to be one of the most concise video on this topic.

Awesome videos, learning Java thru ur videos is a breeze. Small clarification - HashTable is synchronized and shouldn't it be a single thread instead of multiple threads.

[faixan]

We can iterate directly also on entry set rather than saving first in Set.
for(Map.Entry<String, String> i : map.entrySet()) {
" + i.getValue());
}

Thank you so much for such partical and to the point explanation.
Thank you so much over again.

The way of explanation is very crystal clear and understandable

[madanreddy]

One thing is wrong here, in hash map multiple threads will work at a time where as in hash table only single thread at a time( you did a mistake in comparison table )
