Here we know that for >> we use formula as x/2topower of n and for << we use x * 2to power of n

then how we use this for the following one.

class EBH007{
  public static void main (String[] s) {
    byte b = 5; System.out.println(b<<33);
}}

  class EBH005 {
  public static void main (String[] s) {
    byte b = 127; b <<= 2;System.out.println(b);
}}

Hello karthik,
I cannot understand what you are trying to say. But I want to clarify if you don't know.

int b = 127;
b>>i --> b/(2 pow i);
b<<i --> b * (2 pow i);

So if b <<33 it is b * (2 pow 33);

Hope this clarifies your doubt.

b << 33 is equivalent to b << ( 33 % 32) i.e b << 1

just remember this is a topic on the 1.4 exam, but it's NOT on the tiger exam!
