11. 9 key interfaces of Collection framework vii. Map?

 

 

 

previoushomenext

Map is not the child interface of Collection.
If we want to represent a group of individual objects as key value pairs then should go for Map.

Ex:
Roll No                                  Name
101                                         Durga
102                                         Ravi
103                                         Venkat
Both key and value are objects, duplicated keys are not allowed but values can be duplicated.
