It seems IntStream.iterate is just a lightweight ordered version for IntStream.generate.
Is it true? If not, what is the core difference?
Note how their signatures are different:
generatetakes aIntSupplier, which means that you are supposed to generate ints without being given anything. Example usages include creating a constant stream of the same integer, creating a stream of random integers. Notice how each element in the stream do not depend on the previous element.iteratetakes aseedand aIntUnaryOperator, which means that you are supposed to generate each element based on the previous element. This is useful for creating a inductively defined sequence, for example. In this case, each element is supposed to depend on the previous one.
