2284 Sender With Largest Word Count

Question

My Solution:

class Solution {
    public String largestWordCount(String[] messages, String[] senders) {
        Map<String, Integer> freq = new HashMap<>();
        for(int i = 0; i < messages.length; i++){
            freq.put(
                senders[i], freq.getOrDefault(senders[i], 0) + count(messages[i])
                    );
        }
        
        List<String> res = new ArrayList(freq.keySet());
        
        // sorting
        Collections.sort(res, (u1, u2)->freq.get(u1).equals(freq.get(u2))?
                        -u1.compareTo(u2): freq.get(u2) - freq.get(u1)
                        );
        
        return res.get(0);
    }
    
    private int count(String s){
        return s.split("\\s+").length;
    }
}
