我想在使用Java进入该文件夹时从文件夹中复制文件

Question

1. 我希望在下载完成后将文件从我的下载文件夹（主要是文本和一些文件夹）复制到某个特定文件夹。
2. 我想生成一个文本文件，显示有关下载/创建文件的信息。

我使用监视服务来监视该文件夹，并且我编写了用于复制文件的代码。它不起作用。

这是我的代码

import java.util.HashMap;
import java.util.Map;
import java.nio.file.*;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;

public class HiddenProject {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        try (WatchService Service = FileSystems.getDefault().newWatchService()){
            Map<WatchKey, Path> KeyMap = new HashMap<>();
            Path path = Paths.get("C:\\Users\\Pranu\\Downloads");
            KeyMap.put(path.register(Service,
                    StandardWatchEventKinds.ENTRY_CREATE,
                    StandardWatchEventKinds.ENTRY_DELETE,
                    StandardWatchEventKinds.ENTRY_MODIFY),
                    path);

        WatchKey watchkey;
         do {
            watchkey = Service.take();
            Path eventDir = KeyMap.get(watchkey);

            for (WatchEvent<?> event : watchkey.pollEvents()) {
                WatchEvent.Kind<?> kind = event.kind();
                Path eventPath = (Path)event.context();
                System.out.println(eventDir + ":" + kind + " :" + eventPath);

            }
        } while (watchkey.reset());
        } catch (Exception e) {
            ///TODO: handle Exception
        }
    }


    {   

        InputStream inStream = null;
        OutputStream outStream = null;

        try {

            File act1 = new File("C:\\Users\\Praveen\\Downloads\\");
            File act2 = new File("C:\\files\\");

            inStream = new FileInputStream(act1);
            outStream = new FileOutputStream(act2);

            byte[] buffer = new byte[1024];

            int length;
            //copy the file content in bytes 
            while ((length = inStream.read(buffer)) > 0) {
                outStream.write(buffer, 0, length);
            }

            inStream.close();
            outStream.close();

            //delete the original file
            //act1.delete();

            System.out.println("File is copied successful!");

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