包含try和catch以及static String ReadFile的英文文本单词统计的JAVA的代码怎么写

以下是一个包含try和catch以及static String ReadFile的JAVA代码，用于统计英文文本的单词数量：

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashMap;

public class WordCounter {
    
    public static void main(String[] args) {
        String fileName = "textFile.txt";
        String text = ReadFile(fileName);
        HashMap<String, Integer> wordMap = CountWords(text);
        System.out.println("Total number of words: " + wordMap.size());
    }
    
    /*
     * 读取文本文件并返回文本字符串
     */
    public static String ReadFile(String fileName) {
        StringBuilder sb = new StringBuilder();
        try (BufferedReader br = new BufferedReader(new FileReader(fileName))) {
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line).append("\n");
            }
        } catch (IOException e) {
            System.err.println("Exception caught: " + e.getMessage());
        }
        return sb.toString();
    }
    
    /*
     * 统计文本中每个单词的数量并返回一个HashMap
     */
    public static HashMap<String, Integer> CountWords(String text) {
        HashMap<String, Integer> wordMap = new HashMap<>();
        String[] words = text.split("\\s+");
        for (String word : words) {
            Integer count = wordMap.get(word);
            if (count == null) {
                count = 0;
            }
            wordMap.put(word, count + 1);
        }
        return wordMap;
    }
}
