A, B correct.
count(): The count() method returns the count of elements in the stream as a long value. It is a terminal operation that reduces the stream to a single value, which is the count of elements.
collect(): The collect() method is a more general reduction operation that allows you to accumulate elements of a stream into a mutable result container, such as a List, Set, or Map. It takes a Collector as a parameter, which specifies the rules for accumulating the elements. It is also a terminal operation that reduces the stream to a single value, which is the result of the accumulation.
