Reduce Integer.min doesn't return lowest element

PAA :

I am doing some research on the stream reduce and trying to run the very simple program.

Why Integer.min doesn't return the minimum number like Integer.min return the maximum number ?

public class Reducing {
    public static void main(String[] args) {
        List<Integer> numbers = Arrays.asList(3,4,5,1,2);
        Integer sum = numbers.stream().reduce(0, (a, b) -> a+ b);
        System.out.println("REDUCE : "+sum);

        int sum2 = numbers.stream().reduce(0, Integer::sum);
        System.out.println(sum2);

        int max = numbers.stream().reduce(0, (a, b) -> Integer.max(a, b));
        System.out.println("MAX == > "+max);

        int min = numbers.stream().reduce(0, (a, b) -> Integer.min(a, b));
        System.out.println("MIN == > "+min);
    }
}

Output ==>

REDUCE : 15
15
MAX == > 5
MIN == > 0

Aleh Maksimovich :

You are supplying 0 as identity item to min. This value will also used in computations.

int min = numbers.stream().reduce(0, (a, b) -> Integer.min(a, b));

So virtually it is like having

Arrays.asList(0,3,4,5,1,2)

You shuold omit the identity element in your example

int min = numbers.stream().reduce((a, b) -> Integer.min(a, b)).get();
