Эффективное копирование файлов в NIO

Эффективное копирование файлов в NIO:

 // Getting file channels

 FileChannel in = new FileInputStream(source).getChannel();

 FileChannel out = new FileOutputStream(target).getChannel();

 

 // JavaVM does its best to do this as native I/O operations.

 in.transferTo (0, in.size(), out);

 

 // Closing file channels will close corresponding stream objects as well.

 out.close();

 in.close();
