Great video, also this can even be simplify using method reference like this:
-> i * 2).reduce(0, Integer::sum));

Whenever you are referring to any of your previous videos as pre-requisite, i think it's better to provide a link in the video description for the same.

How do we know the initial parameter must be 0 in the reduce method?

[adityakakliya]

Another way to do the same thing -

System.out.println(list.stream().reduce(0, (i, j) -> {
int y = j;
y = y * 2;
return y + i;
}));
