Chapter 3.3 : The Bitwise Operators :

Java defines several bitwise operators , which can be applied to the integer types , long , int, s hort, char, and byte . Bitwise operator works on bits and performs bit-by-bit operation. Assume if a = 60; and b = 13; now in binary format they will be as follows :

a = 0011 1100

 b = 0000 1101

-----------------

a&b = 0000 1100

 a|b = 0011 1101

a^b = 0011 0001

~a = 1100 0011

The following table lists the bitwise operators :

Assume integer variable A holds 60 and variable B holds 13 the n:

Operator	Description	Example
&	Binary AND Operator copies a bit to the result if it exists in both operands .	(A & B) will give 12 which is 0000 1100
|	Binary OR Operator copies a bit if it exists in either operand.	(A | B) will give 61 which is 0011 1101
^	Binary XOR Operator copies the bit if it is s e t in one operand but not both.	(A ^ B) will give 49 which is 0011 0001
~	Binary One s Complement Operator is unary and has the effect of 'flipping ' bits .	(~A ) will give -61 which is 1100 0011 in 2's complement form due to a signed binary number.
<<	Binary Left Shift Operator. The left operands value is move d left by the number of bits specified by the right operand.	A << 2 will give 240 which is 1111 0000
>>	Binary Right Shift Operator. T he left operands value is move d right by	A >> 2 will give 15

	the number of bits specified by the right operand.	which is 1111
>>>	Shift right zero fill operator. T he left operands value is move d right by the number of bits specified by the right operand and shifted value s are filled up with zeros .	A >>>2 will give 15 which is 0000 1111
