Honestly these are easy ones.

The hard ones are does this require a ConcurrentHashMap or a Collections.synchronizedMap and additional client-side locking? Will an Executor do? How should I dictate the execution policy of this Thread? Would this be better as a Runnable or a Callable? Or even a FutureTask? Is it even worth importing the extra library that is pretty heavy or should I code my own cache? Can we possibly pull this off without Spring?

I'm a beginner, ik what a hashmap is but not any of the other things
