In Java how do you sort one list based on another?
I've seen several other questions similiar to this one but I haven't
really been able to find anything that resolves my problem.
My use case is this: user has a list of items initially (listA). They
reorder the items and want to persist that order (listB), however, due to
restrictions I'm unable persist the order on the backend so I have to sort
listA after I retrieve it.
So basically, I have 2 ArrayLists (listA and listB). One with the specific
order the lists should be in (listB) and the other has the list of items
(listA). I want to sort listA based on listB.
