How did you get the return type at 2:45 ? When I do command enter in my intelliJ, it pulls up the info about the Set interface.. and not just show the return type

Nice video... We cannot call stream method on map reference variable

How to iterate if we have map inside map ? It mean if a map inside another map ?

Iteration 2, i get two errors saying that key 'cannot be resolved to a variable', why would that be?
