Java passing arguments (type error)

I have a piece of code that accepts the following:  (List<?extends Object> list)
When I call the code, I need to pass it a List, of course. However, in my code that calls it, I need to piece together the name of that list using String functions (with a String result).  But, the function I am calling needs a List, not a String.

How do pass the argument as a List when actually what I have is a String of the name of the List?

Can your rephrase your question? Why do you have to "piece together the name of the list"? Post a concise and complete example of what you have so far.

You have to find the list based on its name once you've assembled that name, and then pass the found list to your method. You could keep your lists in a Map if you like.
