最常出现的词显示

Question

我有一个问题，因为我每次评价只拿60分，如果我有两个单词相同的次数，我不知道如何显示字典最小值。我实际上必须显示文本中最常见的单词，如果有两个单词出现次数相同以显示词典最小值。我真的不知道如何使用 HashMap 来做到这一点，修复？这是我的代码！

import java.io.*;
import java.util.*;
public class Main {
public static void main(String[] args) {
    Map < String, Integer > map = new LinkedHashMap < String, Integer > ();
    BufferedReader reader = null;
    try {
        reader = new BufferedReader(new InputStreamReader(System.in));
        String currentLine = reader.readLine();
        while (currentLine != null) {
            String[] input = currentLine.replaceAll("[^a-zA-Z]", " ").toLowerCase().split(" ");
            currentLine.replace('\n', ' ');
            for (int i = 0; i < input.length; i++) {
                if (map.containsKey(input[i])) {
                    int count = map.get(input[i]);
                    map.put(input[i], count + 1);

                } else {
                    map.put(input[i], 1);
                }

            }
            currentLine = reader.readLine();
        }
        String mostRepeatedWord = null;
        int count = 0;
        for (Map.Entry < String, Integer > m: map.entrySet()) {
            if (m.getValue() > count) {
                mostRepeatedWord = m.getKey();
                count = m.getValue();
            }
            else if (m.getValue() == count) {
                mostRepeatedWord = m.getKey();
                count = m.getValue();
                if ()
            }
        }
        System.out.println(mostRepeatedWord);

    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        try {
            reader.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

您还可以将 mostRepeatedWord 与当前键进行比较，以防循环本身出现平局，如下所示：

String mostRepeatedWord = null;
int count = 0;
for (Map.Entry < String, Integer > m: map.entrySet()) {
    if (m.getValue() > count) {
        mostRepeatedWord = m.getKey();
        count = m.getValue();
    } else if (m.getValue() == count) {
        String key = m.getKey();
        if ( key.compareTo(mostRepeatedWord) ) < 0 {
            mostRepeatedWord = key;
        }
    }
}
