I am not sure if the following is doable:
I have say a hashmap - key:"1" value: "one".
I want to convert this hashmap to a list - ["1":"one"]
Is this doable?

Yes. You can iterate over the map and insert them into the list.

The entrySet() method of the Map interface should be of help.

Do you really want a List? There is no particular order to the entries in a Map. You can use a hybrid list and Map of you wish to introduce an ordering.
