TCCICOMPUTERCOACHING.COM  BufferedReader and InputStreamReader are both Input Function in Java File.  BufferedReader reads a couple of characters from the specified stream and stores it in a buffer. This makes input faster.  InputStreamReader reads only one character from specified stream and remaining characters still remain in the stream.

TCCICOMPUTERCOACHING.COM Example: c l a s s Ne wClass { p u b l i c s t a t i c v o i d main(String args[]) throws Interru pte dE xception, I OE xception { Â BufferedReader isr = n e w BufferedReader( n e w I nputStreamRe ade r(System. i n )); Scanner sc = n e w Scanne r(Sy stem. i n ); System. o u t .println("B.R. - "+( c h a r )isr.rea d()); System. o u t .println("Scanne r - " + sc.nextLin e()); } }

TCCICOMPUTERCOACHING.COM  When the isr.read() statement is executed, I entered the input

”hello” and the character “h” of “hello” is printed on the screen. If this was InputStreamReader then the remaining characters “ello” would have remained in the System.in stream and the sc.nextLine() would have printed them. But in this case it doesn’t happens because the BufferedReader reads all of the “hello” characters from the System. in stream and stores them in its own personal buffer and thus the System. In stream remains empty when sc.nextLine() is executed.
