是否有简单的Java逻辑来处理同一目录中预先存在的文件和新创建的文件？

import java.io.IOException;
import java.nio.file.*;

public class FileWatcher {
    public static void main(String[] args) {
        try {
            // 创建WatchService对象
            WatchService watchService = FileSystems.getDefault().newWatchService();

            // 注册监听的目录
            Path directory = Paths.get("目录路径");
            directory.register(watchService, StandardWatchEventKinds.ENTRY_CREATE, StandardWatchEventKinds.ENTRY_MODIFY);

            // 启动监听线程
            Thread watchThread = new Thread(() -> {
                try {
                    while (true) {
                        WatchKey key = watchService.take(); // 获取文件系统事件
                        for (WatchEvent<?> event : key.pollEvents()) {
                            WatchEvent.Kind<?> kind = event.kind();
                            if (kind == StandardWatchEventKinds.ENTRY_CREATE) {
                                // 处理新创建的文件
                                Path filePath = directory.resolve((Path) event.context());
                                System.out.println("新创建的文件：" + filePath);
                            } else if (kind == StandardWatchEventKinds.ENTRY_MODIFY) {
                                // 处理修改的文件
                                Path filePath = directory.resolve((Path) event.context());
                                System.out.println("修改的文件：" + filePath);
                            }
                        }
                        key.reset(); // 重置WatchKey
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            });
            watchThread.start();

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
