    Java streams 

    public static void plusMinus(List<Integer> arr) {

    long negValues = arr.stream().filter(x -> x < 0).count();
    long posValues = arr.stream().filter(x -> x > 0).count();
    long zeroValues = arr.stream().filter(x -> x == 0).count();
    long length = negValues + posValues + zeroValues;
    
    
    System.out.println((double)posValues/length);
    System.out.println((double)negValues/length);
    System.out.println((double)zeroValues/length);

    }
