About Question enthuware.ocpjp.v8.2.2022 :

[d0wnvk@gmail.com]

IntStream is2 = IntStream.of(2, 4, 6); //4
int y = is2.filter( i->i%2 != 0 ).sum(); //5
System.out.println(y); //6

is line //5 really returns 12 ?

I mean 4%2 == 0, which means
filter( i->4%2 != 0 ) returns false.

Where is I am wrong ?

An element will be removed from the stream if the condition is true. If i%2 is 0 then the condition is not true and so element will NOT be removed.

Please fix the explanation, result is 0 for the following snippet of code:

Code: Select all

IntStream is2 = IntStream.of(2, 4, 6); //4 
int y = is2.filter( i->i%2 != 0 ).sum(); //5 
System.out.println(y); //6
