Why do we use BufferedReader and InputStreamReader?

In the video, we create a reader to handle user input:

mReader = new BufferedReader(new InputSteamReader(System.in));

Why do we use this approach instead of using the console or other methods we came across previously? This part wasn't clear to me in the video.

  1. It's another approach to I/O that's common in Java.

  2. The program also used in the Local Development Environments course. IDE's have trouble with Console so you need to use this method to get it to work.
