Re: Why Stream.concat is a static method - type variable contravariance

Stream.of(specialElement).append(remainingStream).collect(toList()); has better "flow" than Stream.concat(Stream.of(specialElement), remainingStream).collect(toList()); Regards, Tomasz Linkowski On Mon, Oct 15, 2018 at 4:51 AM Tagir Valeev wrote: > Hello! > > Still from

but "Collectors.compositing" looks a bit strange. "Collectors.composing" seems much better to me, but - as far as I understand - there was some concern that the users could misunderstand it as element-wise composition, is that right? Regards, Tomasz Linkowski [1] https://en.wikipedi
