What is the consequence of calling `parallel()` on a stream with a stateful intermediate operation like `sorted()`?

Explanation

Calling `parallel()` on a stream with a stateful operation like `sorted()` forces the stream to collect all elements to determine order before proceeding. This can eliminate the benefits of parallelism, potentially making the execution slower than sequential.

Key points

Stateful operations like `sorted()` require collecting all elements before proceeding in a parallel stream
This can reduce or eliminate the benefits of parallel execution
It may result in slower performance compared to sequential execution
