If I have a stream of [a, b, c, d] what’s a simple and idiomatic way to transform this into a stream of pairs [[a, b], [c, d]]

does this work on streams as well?

[rrva]

without collecting the stream first

[Andreas Sinz]

are we talking about Java-Streams or Kotlin Sequences?

Java-streams

[Andreas Sinz]

you have three choices:
1. replace Stream with Sequence and use chunked
2. stream.toSequence().chunked(2).toStream()
3. ask on stackoverflow or somewhere else how to do it in pure java
