In CacheComputeManager, implement the logic of the empty method. Guess what it should do based on the method name and the class's logic.

Found this one to be extremely difficult due to opaque use of generics, and FutureTask always confuses me a lot. I get Thread and Runnable, but Future/FutureTask/Callable always confuse me. It also probably doesn't help that I haven't done a task with Future/FutureTask in many months. I stared at it for a few days and realized I was never going to figure out on my own how to even begin it, so I had to look at the solution. For me, this one was definitely in the solid red Difficult category.

Don't use lambda for this one, validator won't accept it :) I encourage to check out Intellij lambda replacement tho, so it will be easier to understand how these work.
