java - 如何按所有类型的标点符号拆分 ArrayList 中的文本文件？

Question

到目前为止，这是我的代码:

import java.util.*;
import java.io.*;

public class Alice {

    public static void main(String[] args) throws IOException {

        /*
         * To put the text document into an ArrayList
         */
        Scanner newScanner = new Scanner(new File("ALICES ADVENTURES IN WONDERLAND.txt"));

        ArrayList<String> list = new ArrayList<String>();

        while (newScanner.hasNext()) {
            list.add(newScanner.next());
        }
        newScanner.close();
    }
}

我对现在如何通过所有标点符号拆分文档感到困惑，但我仍然需要能够对文本中的单词执行字符串操作。请帮忙

输入是整本爱丽丝梦游仙境书，我需要输出如下:

“这本书是为了使用等。”

基本上所有的单词都是分开的，所有的标点符号都从文档中删除。

List <String> list = new ArrayList <> ();
Pattern wordPattern = Pattern.compile ("\\w+");
try (BufferedReader reader = new BufferedReader (new FileReader ("ALICES ADVENTURES IN WONDERLAND.txt"))) {
    String line;
    while ((line = reader.readLine ()) != null) {
        Matcher matcher = wordPattern.matcher (line);
        while (matcher.find())
            list.add (matcher.group());
    }
}
