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
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 set in one operand but
not both.
|
(a ^ b) will give 49 which is
0011 0001
|
~
|
Binary Ones Complement operator is unary and has the effect of
‘flipping’ bits.
|
(~a) will give -60 which is 1100 0011
|
<<
|
Binary Left Shift Operator. The left operands value is moved left by
the number of bits specified by the right operand.
|
a << 2 will give 240 which is 1111 0000
|
>>
|
Binary Right Shift Operator. The left operands value is moved right
by the number of bits specified by the right operand.
|
a >> 2 will give 15 which is
0000 1111
