This question is a continuation of this thread:

In short: To solve my problem, I want to use Map<Set<String>, String>.

However, after I sort my data entries in Excel, remove the unnecessary parameters, and the following came out:

flow content ==> content content 
flow content ==> content depth distance 
flow content ==> content depth within 
flow content ==> content depth within distance 
flow content ==> content within 
flow content ==> content within distance 

I have more than one unique key for the hashmap if that is the case. How do I go around this... anyone have any idea?

I was thinking of maybe Map<Set <String>, List <String>> so that I can do something like:

Set <flow content>, List <'content content','content depth distance','content depth within ', ..., 'content within distance'>

But because I am parsing the entries line by line I can't figure out the way how to store values of the same repeated keys (flow content) into the same list and add it to the map.

Anyone have a rough logic on how can this be done in Java?

Thanks in advance.
