将文件移动到特定文件夹 [英] Move a file to a specific folder

问题描述

我正在尝试将文件移动到指定的文件夹，但我不能。

这是代码：

  public   static   void  moveToRightDirectory（文件歌曲，字符串专辑）抛出 IOException {
 album = album。修剪（）; 
 字符串 pathDirectory = selectedDir +   \ \ +专辑; 
 File dir =  new 文件（pathDirectory）; 
 System.out.println（  dir.exists（）： + dir.exists （））; 
  if （dir.exists（））{
 Files.move（song.toPath（），dir.toPath（），StandardCopyOption.REPLACE_EXISTING ）; 
  //   System.out.println（song.renameTo（dir））;  
} 
  else  {
  boolean  success =（ new 文件（pathDirectory））。mkdirs（）; 
  if （！success）{
 System.out.println（ < span class =code-string>创建目录时出错。）; 
} 
  else  {
 Files.move（song.toPath（），dir.toPath（），StandardCopyOption.REPLACE_EXISTING）; 
  //   System.out.println（song.renameTo（dir））;  
  //   FileUtils.moveFile（song，dir）;  
} 
 } 
} 

我想将歌曲文件移到文件夹中DIR 的。为此，我尝试了几种方法：



- Files.move - >生成以下错误：

 java.nio.file.FileSystemException：C：\ Users \ pi \Desktop \\ \\Adele1 \Cold shoulder.mp3  - > C：\Users\ila\Desktop\Adele1 \19：进程无法访问该文件，因为它正由另一个进程使用。

- song.renameTo（dir） - >它什么都不做。



- FileUtils.moveFile（song，dir） - > Eclipse找不到 FileUtils 。我做了 java.lang.Object.org.apache.commons.io.FileUtils 的导入，但错误变成导入 java.lang.Object.org 不能得到解决。



如何解决？

非常感谢。

I'm trying to move a file to a specified folder but I can't.
This is the code:

public static void moveToRightDirectory(File song, String album) throws IOException {
	    album = album.trim();
	    String pathDirectory = selectedDir + "\\" + album;
	    File dir = new File(pathDirectory);
	    System.out.println("dir.exists(): " + dir.exists());
	    if(dir.exists()) { 
	      Files.move(song.toPath(), dir.toPath(), StandardCopyOption.REPLACE_EXISTING);
	      //System.out.println(song.renameTo(dir));
	    }
	    else { 
	      boolean success = (new File(pathDirectory)).mkdirs();
	      if(!success) {
	        System.out.println("Error creating directory.");
	      }
	      else {
	        Files.move(song.toPath(), dir.toPath(), StandardCopyOption.REPLACE_EXISTING);
	        //System.out.println(song.renameTo(dir));
	        //FileUtils.moveFile(song, dir);
	      }
	    }
	  }

I would like to move the song file in the folder dir. To do this I have tried several methods:

- Files.move -> The following errors are generated:

java.nio.file.FileSystemException: C:\Users\ila\Desktop\Adele1\Cold shoulder.mp3 -> C:\Users\ila\Desktop\Adele1\19: The process cannot access the file because it is being used by another process.

- song.renameTo(dir) -> It does nothing.

- FileUtils.moveFile(song, dir) -> Eclipse does not find FileUtils. I did the import of java.lang.Object.org.apache.commons.io.FileUtils but the error becomes "The import java.lang.Object.org can not be resolved."

How can I fix?
Thanks a lot.
