@ianandrewclark Don't call

.stream()

it gives you a java stream not a kotlin list, you should be able to call

.forEach { println(it) }

directly on the collection.

Am I missing context? Why would you suggest mapping the stream contents with

println

? Might he not need the list for something else?

My apologies, I made an assumption he was try to convert something to a list in order to perform some sort of list functions on it. map/filter/foreach. Furthermore if he can call stream on the object then isn't it most likely already a collection?

Sorry, I’m getting the Stream from a BufferedReader.lines() method

hmm, there’s supposed to be an extension function,

BufferedReader#lineSequence()

, provided by Kotlin, but I’m not sure that’ll be terribly helpful if you can’t use any of the extension methods

Hmm, let me check that out…

np @Ian. Might be worth mentioning that the source for that method includes this comment:

We suggest you try the method [useLines] instead which closes the stream when the processing is complete.

I’m not sure if this is directly relevant to you, but it may be worth investigating

Yes, in this case I actually needed a

List

, so toList() worked out fine 🙂
