About Question enthuware.ocpjp.ii.v11.2.3333 :

[sirtomash]

I think this option is not correct not only because of lack of getAsDouble() call:

Code: Select all

 
double average = nums.parallelStream().mapToInt(i->i).average();

also parallelStream() is not correct for Stream. I guess this shall be

Code: Select all

double average = nums.parallel().mapToInt(i->i).average().getAsDouble();

I see that it has already been changed to parallel. Which question bank are you using?

[teodorj]

double average = nums.parallelStream().mapToInt(i->i).average();

In 817, it is not changed to parallel()
question bank version 1/21

Explanation has now been added to include this point as well.
