如何从HashMap中仅打印前10个单词及其出现频率？

import java.util.*;

public class WordFrequency {
    public static void main(String[] args) {
        // 创建HashMap对象
        HashMap<String, Integer> wordMap = new HashMap<>();

        // 文本内容
        String text = "This is a sample text. It contains some words that may repeat. This is just a sample.";

        // 将文本中的单词及其频率存储在HashMap中
        String[] words = text.split(" ");
        for (String word : words) {
            if (wordMap.containsKey(word)) {
                wordMap.put(word, wordMap.get(word) + 1);
            } else {
                wordMap.put(word, 1);
            }
        }

        // 创建ArrayList对象，用于存储HashMap中的键值对
        ArrayList<Map.Entry<String, Integer>> wordList = new ArrayList<>(wordMap.entrySet());

        // 对ArrayList进行排序，按值的大小降序排列
        Collections.sort(wordList, new Comparator<Map.Entry<String, Integer>>() {
            public int compare(Map.Entry<String, Integer> o1, Map.Entry<String, Integer> o2) {
                return o2.getValue().compareTo(o1.getValue());
            }
        });

        // 打印前10个单词及其出现频率
        int count = 0;
        for (Map.Entry<String, Integer> entry : wordList) {
            System.out.println(entry.getKey() + ": " + entry.getValue());
            count++;
            if (count == 10) {
                break;
            }
        }
    }
}
