 It adds more efficiency than to write data directly
 into a stream. So, it makes the performance fast.

Java BufferedInputStream Class
Java BufferedInputStream class is used to read information 
from stream. It internally uses buffer mechanism to make 
the performance fast.

The important points about BufferedInputStream are:

When the bytes from the stream are skipped or read, 
the internal buffer automatically refilled from the contained 
input stream, many bytes at a time.
When a BufferedInputStream is created, an internal buffer 
array is created.
