Which of the following statements is true about using parallel streams with a List collection?

C. Parallel streams can improve performance for large collections. Here's a breakdown of the statements and why they're true or false: A. False: Parallel streams do not guarantee processing elements in order. They split the collection into smaller chunks and process them concurrently on multiple threads, potentially leading to out-of-order processing. B. False: Parallel streams are not inherently thread-safe for modifications to the original List. If you need to modify the List within the stream operations, you must use appropriate synchronization mechanisms like collect with a suitable collector or use a concurrent collection class like CopyOnWriteArrayList C. True: Parallel streams can significantly improve performance for large collections (> 10,000 elements) by utilizing multiple cores on your CPU. They split the work of processing elements across threads, potentially leading to faster execution. However, the performance gain depends on various factors like the size of the collection, the nature of the operations performed in the stream, and the overhead of thread management. D. False: Not all operations in a parallel stream require explicit synchronization. Operations like filter(), map(), and forEach (used for side effects without modification of the original List) can be performed in parallel without explicit synchronization. However, if you need to modify the original List or perform operations with potential state dependencies, synchronization might be necessary.
