Which operation is NOT directly supported by the Map interface?

Retrieving a value based on key
Retrieving an ordered list of keys
Adding a key-value pair
Removing a key-value pair

The correct answer is: Retrieving an ordered list of keys

The map interface does not directly support retrieving an ordered list of keys, as it is a data structure that stores elements in a key-value pair format. The other options (A, C, D) are all directly supported by the map interface. Option A allows you to retrieve a value based on a given key, option C allows you to add a new key-value pair to the map, and option D allows you to remove an existing key-value pair from the map.
