Question

In my program I need a for-each loop which counts the number of evens in the given array and increments the variable even for each one. When I use a standard

Answer 1

Though there are lot many answers. You could achieve same by using java-8 streams as well. Use reducer to find out the even's count and then from length reduce the even's count to get odd's count.

See code below:-

   int[] numbers = new int[8];

    for (int i = 0; i < numbers.length; i++) {
        numbers[i] = (int) (Math.random() * 51 + 50);
    }

    int even = Arrays.stream(numbers)
            .reduce(0, (a, b) -> {
                a += b % 2 == 0 ? 1 : 0;
                return a;
            });
    int odd = numbers.length - even;
