[@samiahmad5612]

00:03 Map provides a way to associate values with unique keys. 01:22 Using a map to store key-value pairs 02:40 Data types and class for implementing a hashmap 03:53 Map data structure in Java 05:01 Keys are unique, values can be the same 06:19 Print all values using a for loop 07:38 You can print all the values from a map using the get method. 08:55 Hash table and hash map are similar but hash table is synchronized while hash map is not.

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 ?

At 2:17 you clicked on the Map reference and it pulled up what looks like the java docs for the Map class. Is that an extension that you have installed?

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.
