java实现热搜词语

以下是Java实现热搜词语的示例代码：

import java.util.*;

public class HotSearch {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        Map<String, Integer> hotWords = new HashMap<>();
        while (true) {
            System.out.println("请输入热搜词语：");
            String word = scanner.next();
            if (word.equals("exit")) {
                break;
            }
            if (hotWords.containsKey(word)) {
                hotWords.put(word, hotWords.get(word) + 1);
            } else {
                hotWords.put(word, 1);
            }
            System.out.println("当前热搜词语排行榜：");
            List<Map.Entry<String, Integer>> list = new ArrayList<>(hotWords.entrySet());
            Collections.sort(list, (o1, o2) -> o2.getValue().compareTo(o1.getValue()));
            for (int i = 0; i < list.size(); i++) {
                System.out.println((i + 1) + ". " + list.get(i).getKey() + "：" + list.get(i).getValue());
            }
        }
    }
}
