[In Java] Difference between 'FileReader' and 'BufferedReader'

Hi I'm Rio.

The Following paragraph is quoted from http://www.oopweb.com/Java/Documents/JavaNotes/Volume/chap84/ch84_3.html. 

Difference between 'FileReader' and 'BufferedReader'

Point is that BufferedReader is a Rapping class around Reader like FileReader.

In this pic, FileReader reads file into 8-bit. But BufferedReader stores data and tranfers that as 16-bit. So I think, if it is not special case, Using BufferedReader is more efficient.

Thanks.
