Haha, I bet the exam writer is just trying to confuse us with all these stream operations. As long as I can remember to use map() to get the techName field, I should be good to go!

I'm not sure why we need to use forEachOrdered() in options C and D. Isn't that just for maintaining the original order of the stream?

Option B looks like the correct answer to me. The stream needs to be mapped to the techName field before printing it out.

I'm not sure, but I think D could also work since it ensures the elements are printed in order.

I agree with Stephaine, because we need to map the techName before printing.
