Question

I was refactoring some old code of mine that I\'ve written and I stumbeled on this code:

    List fullImagePool = new ArrayList<>();
           


        

Answer 1

In Java 8 Use below code:-

Optional.ofNullable(listToBeAdded).ifPresent(listToBeAddedTo::addAll)

listToBeAdded - The list whose elements are to be added. listToBeAddedTo - The list to which you are adding elements using addAll.
