Java file copying

using java.nio for super-speedy copies. More readable and less prone to errors than using Input/Output stream pairs and a byte buffer

// Create channel on the source
FileChannel srcChannel = new FileInputStream("srcFilename").getChannel();
// Create channel on the destination
FileChannel dstChannel = newFileOutputStream("dstFilename").getChannel();
// Copy file contents from source to destination
dstChannel.transferFrom(srcChannel, 0, srcChannel.size());
// Close the channels
} catch (IOException e) {
