Solved HashMap 3 parameters?

Hello, I am trying to figure out a way that would allow me to use a hashmap with 3 parameters.
(HashMap<param1,param2,param3>)
I want to create a map that will take the parameters UUID, List<String>, [].
How would I accomplish this and any help is greatly appreciated.

 

What is the third parameter for? Also in general what are you attempting to accomplish.

You can make a map that has a map inside like:

Map<UUID, map<integer, string>

But I don't believe that's what you're looking for.

If you wanted to create a system that requires two variables to give a third, turn the key into an object that can store both of the two variables.

If your intention was to create a system that takes in one variable and returns two, turn the value into an object that can store both of the variables.
