Question

What is the difference between a parallel stream and a sequential stream?

a) A parallel stream is more efficient than a sequential stream.

b) A parallel stream processes elements in parallel, while a sequential stream processes elements sequentially.

c) A parallel stream is always unordered, while a sequential stream is always ordered.

d) A parallel stream is always lazy, while a sequential stream is always eager.
