Compare two integer arrays using java stream

I have two arrays of integers, for example –

int [] a = {2,7,9}

int [] b = {4,2,8}

I want to compare it element by element, that is, 2 to 4, then 7 to 2, and finally 9 to 8 Each comparison result is stored in a list

It's easy to do this using traditional Java methods But I want to use stream here Do you have any pointers?

Solution

You can do this,

List<Boolean> equalityResult = IntStream.range(0,a.length).mapToObj(i -> a[i] == b[i])
                .collect(Collectors.toList());

Prerequisite: the two arrays are the same size
