This is how I solve this problem in java:

public static List<Integer> compareTriplets(List<Integer> a, List<Integer> b) {

    if(a.size() != b.size()){
        throw new IllegalArgumentException("Both lists size are not same!");
    }

    List<Integer> result = new ArrayList<>();
    int bob = 0;
    int alice = 0;

    int size = Math.min(a.size(), b.size());

    for(int i = 0; i < size; i++) {

        if(a.get(i) > b.get(i)){ 
            System.out.println("Alice recieve a point");
            alice+= 1;
        }
        else if(a.get(i) < b.get(i)){
            System.out.println("Bob recieves a point");
            bob+=1;
        } 
        else if(a.get(i).equals(b.get(i))){
            System.out.println("Neither Bob or Alice recieve a point");
        }

    }
    result.add(alice);
    result.add(bob);

    return result;

}
