I thought this was a question about cooking recipes, not Java programming! Guess I need to brush up on my programming skills before the next exam.

Option D looks good, but it's unnecessary to use mapToInt() to convert the String elements to integers. The filter() method alone should do the trick.

Option C is interesting, but the peek() method is used for side effects, not for filtering. It wouldn't give us the correct count.

That's correct. The filter method will only keep elements with a length greater than 3.

Option B doesn't seem right because the map() method is used to transform the elements, not to filter them. The count() method would return the number of elements that are true, which is not what we want.

User3: Yeah, option A is the right choice. It filters the elements with length greater than three and then counts them.

Yes, using mapToInt() after filter() will give us the count of elements with length greater than three.

That makes sense, we want to filter out the elements with length greater than three.

I think option A is the correct answer. The stream() method is used to create a stream of the list elements, and the filter() method is used to filter the elements based on the condition x.length() > 3, which gives us the count of the string elements whose length is greater than three.

I agree with Ressie. Option A makes sense as it filters the elements based on length and then counts them.

I think the answer is A) listVal.stream().filter(x -> x.length()>3).count(). Because it filters out the elements with length greater than three and then counts them.
