如何按所有类型的标点符号拆分ArrayList中的文本文件？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.regex.Pattern;

public class TextFileSplitter {
    public static void main(String[] args) {
        ArrayList<String> files = new ArrayList<String>();
        files.add("file1.txt");
        files.add("file2.txt");
        
        ArrayList<String> result = new ArrayList<String>();
        
        for (String file : files) {
            String content = readFile(file);
            String[] words = splitTextByPunctuation(content);
            
            result.addAll(Arrays.asList(words));
        }
        
        // 输出结果
        for (String word : result) {
            System.out.println(word);
        }
    }
    
    // 读取文件内容到字符串
    public static String readFile(String filename) {
        StringBuilder content = new StringBuilder();
        
        try (BufferedReader reader = new BufferedReader(new FileReader(filename))) {
            String line;
            while ((line = reader.readLine()) != null) {
                content.append(line);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        
        return content.toString();
    }
    
    // 使用正则表达式拆分文本
    public static String[] splitTextByPunctuation(String text) {
        return text.split("(?<=\\p{Punct})|(?=\\p{Punct})|\\s+");
    }
}
