Wait, why are we printing out 'Java-Oracle DB-J2EE-' instead of 'Java', 'Oracle DB', and 'J2EE'? Sounds like the exam writer has a weird sense of humor.

Option D seems a bit too straightforward, doesn't it? I bet the answer is something a little more complex, like Option B.

I agree with you. Sometimes the simplest solution is the most effective. Option D is the way to go in this case.

I think you might be right. Option B does seem like a more complex solution, but sometimes the straightforward answer is the best one.

Option D is actually the correct answer. It will print Java-Oracle DB-J2EE- in the correct order.

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!
