如何将Java nio文件walk()结果存储到字符串列表中？

import java.io.IOException;
import java.nio.file.*;
import java.util.ArrayList;
import java.util.List;

public class FileWalker {
    public static void main(String[] args) {
        String directory = "path/to/directory"; // 替换为实际的目录路径

        List<String> fileList = new ArrayList<>();

        try {
            Files.walk(Paths.get(directory))
                    .filter(Files::isRegularFile)
                    .forEach(file -> fileList.add(file.toString()));
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 打印文件列表
        for (String file : fileList) {
            System.out.println(file);
        }
    }
}
