The best way is to use an integer range of the right size and map each
int into an object of your choice. For example, to get a stream consisting of 20 copies of the string “x”, do the following:
IntStream.range(0, 20).mapToObj(i -> "x")
An alternative is to create a collection using
Collections.nCopies and then stream that:
This is actually implemented using
IntStream.range; however, it may be a bit more intuitive.
