    List<Boolean> result = new ArrayList<Boolean>();
    int max = 0;

        if(candies[i] + extraCandies > max) {
            return result.add(false);
        }
        else {
            return result.add(true);
        }
    }
    
    return result;

You should remove the return before the result.add(...). Otherwise, you try to return the value you just added to the list, instead of returning the list itself like you want.
