Copy Contents of a Directory with Java

In my Java program I have 2 paths (Strings) of 2 different directories.

I want a method to copy all the files from one directory to the other. (just the contents, not the folder).

How can I do that?

Can use

org.apache.commons.io.FileUtils;

Collection getAllFilesThatMatchFilenameExtension(String directoryName, String extension)
{
  File directory = new File(directoryName);
  return FileUtils.listFiles(directory, new WildcardFileFilter(extension), null);
}

loop through the collection and call 

   FileUtils.copyFileToDirectory(file, destinationDir);

Make a class that extends SimpleFileVisitor<Path> and override its methods. visitFile should copy the file to the new directory and the VisitDirectory methods should just continue down the tree. Then use the new class with Files.walkFileTree.
