Copy file from one folder to another in java

问题

I am trying to copy a file from one folder to another folder.

Here's what I have got in my code:

public static void copyFile(String path) throws IOException{
   newPath = path;    
   File destination = new File ("E:/QA/chart.js"); 
   FileUtils.copyFile(destination, new File(newPath));      
}

But it is not copying the desired file to its location. What is required, its copy chart.js from E drive and copy to the newPath variable location. Is there some other way to copy files from one place to another?

回答1:

You can use standard java.nio.file.Files.copy(Path source, Path target, CopyOption... options)

回答2:

You can use this

Path FROM = Paths.get(Your Source file complete path);
Path TO = Paths.get(Destination complete path);
CopyOption[] options = new CopyOption[]{
  StandardCopyOption.REPLACE_EXISTING,
  StandardCopyOption.COPY_ATTRIBUTES
}; 
java.nio.file.Files.copy(FROM, TO, options);

回答3:

Try this.

FileUtils.copyFile(src, dest)

this is happening in copy. so this point of view File src = new File ("E:/QA/chart.js"); assume src file existing one. Then you create a new destination file like this

File dest = new File(newPath);
if(!dest.exists())
  dest.createNewFile();

Then you can copy

FileUtils.copyFile(src,dest);
