我正在使用 Vue.js 3，但由于此错误，我无法使用 Vue-chartjs 制作图表：

Uncaught TypeError: createElement is not a function

这是显示我的图表的 App.vue：

<template>
  <line-chart />
</template>

<script>
import LineChart from "./components/Chart";
export default {

  name: "App",
  components: {
    LineChart
  }
};
</script>

这是呈现折线图的 Chart.vue：

<script>
import { Line } from "vue-chartjs";
export default {
  extends: Line,
  data: () …

我想编写一个程序，例如显示文本中重复次数最多的 5 个单词。保存在地图中的文本的单词，其键是单词，其值是重复该单词的次数。

该程序显示重复最多的单词，但我不知道如何改进以显示 5 个重复最多的单词（以及如何使用地图而不是列表）。

import java.io.BufferedReader;    
import java.io.FileReader;    
import java.util.ArrayList;    

public class MostRepeatedWord {    

    public static void main(String[] args) throws Exception {    
        String line, word = "";    
        int count = 0, maxCount = 0;    
        ArrayList<String> words = new ArrayList<String>();    

        //Opens file in read mode    
        FileReader file = new FileReader("data.txt ");    
        BufferedReader br = new BufferedReader(file);    

        //Reads each line    
        while((line = br.readLine()) != null) {    
            String string[] = line.toLowerCase().split("([,.\\s]+) ");    
            //Adding all words generated in previous step into words …
