Java Scanner vs BufferedReader?

I know both Scanner and BufferedReader in Java. However, although Scanner is easier to get user input (e.g. already converts user's input to a specific data type), and is shorter to initialize, I was taught to use BufferedReader.

Is there a benefit to using BufferedReader as compared to Scanner? I've always wondered this.

Hi. It is been a while when I last time used Java, but I think I do remember something about those.

When you want simple way to get user input from keyboard, Scanner is simpler and basicly as fast as BufferReader.
For a console questions such as "What is your name", or "What is your age", Scanner is easy way to go with.

But when data size or type may varieate, BufferReader comes more handy and faster. For bigger size, BR also needs less sys calls making it faster.

Reading large files: Go with BR
Input processing: Go with BR
RAM usage: Go with BR
Simple user input via console: Use scanner
Simplicity: Scanner

This is how I remember these, but it was 2013 when I actually learned Java last time...
