As you wrote yourself already: each has its own use; a DataInputStream can read primitive values in their binary form. A Scanner can read those in their textual form. A BufferedReader is a text only thing and its real functionality is the buffering of the (text) data. You can't say which one is best because those classes have different functionality.

kind regards,
