如何仅使用扫描仪读取文件并将每个句子存储在arrayList中？

import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;

public class ScannerExample {
    public static void main(String[] args) {
        // 读取扫描文件
        File scanFile = new File("scan.txt");
        ArrayList<String> sentences = new ArrayList<>();

        try {
            Scanner scanner = new Scanner(scanFile);
            scanner.useDelimiter("[.?!]"); // 设置句子分隔符为句号、问号、感叹号
            while (scanner.hasNext()) {
                String sentence = scanner.next().trim();
                sentences.add(sentence);
            }
            scanner.close();
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        }

        // 打印存储的句子
        for (String sentence : sentences) {
            System.out.println(sentence);
        }
    }
}
