具体实现

public class HJ094 {

    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        int m = Integer.valueOf(sc.nextLine());
        String[] candidates = sc.nextLine().split("\\s+");

        int n = Integer.valueOf(sc.nextLine());
        String[] votes = sc.nextLine().split("\\s+");

        count(candidates, votes);
    }

    public static void count(String[] candidates, String[] votes) {
        String temp = "Invalid";
        Map<String, Integer> map = new HashMap<>();
        for (int i = 0; i < candidates.length; i++) {
            map.put(candidates[i], 0);
        }
        for (int i = 0; i < votes.length; i++) {
            if (map.containsKey(votes[i])) {
                map.put(votes[i], map.get(votes[i]) + 1);
            } else {
                map.put(temp, map.getOrDefault(temp, 0) + 1);
            }
        }

        for (String key : candidates) {
            System.out.println(key + " : " + map.get(key));
        }
        System.out.println(temp + " : " + map.getOrDefault(temp,0));

    }
}
