Example : input : { a, b, k, {A, c, G, H, p}}
output : {a, b, k, {c, p}} . How to write stream fn for this. Expection is to remove capital letter from list.

What do you mean by more readable?
In the summation example using iterative approach is also much more readable and verbose also, while in streams if some complex operation is being performed, you cannot debug the intermediate state until terminal operation is performed.

Traditional approach can be understood by even grade 10 student if he has learnt any programming language, why do we call streams more readable?
