I suggest to all viewers to check internal implementation of maps, these data structures are way different than they looks and not discussed even 1% in this video. Though this video gives nice information to start working with Maps.

[@anant8321]

Can you suggest any videos for the implementation purpose ?

Sir, What if you have 2 or more student of same name in this example? how can we add new one instead of updating previous one.

[@Mshagy02]

Use a more discriptive key. for example use first and last name of the student

[@VeluR-1993]

What if one key has multiple value. How to get the values. Please help.
