Groovy: Bitwise operators

Below table summarizes the bitwise operators provided by Groovy.

Operator	Performs	Description
&	and	a & b
|	or	a | b
^	xor (Exclusive-OR)	a ^ b
~	negation	~a

Bit Wise AND(&), OR(|), Exclusive OR(^)

Below table summarizes the bitwise operators.

Bit1	Bit2	&	|	^
0	0	0	0	0
0	1	0	1	1
1	0	0	1	1
1	1	1	1	0

HelloWorld.groovy

a = 8
b = 9

println "a & b : ${a & b}"
println "a | b : ${a | b}"
println "a ^ b : ${a ^ b}"

Output

a & b : 8

a | b : 9

a ^ b : 1

Explanation

   a    = 0000 1000

   b    = 0000 1001

   a&b = 0000 1000

   a    = 0000 1000

   b    = 0000 1001

   a|b = 0000 10001

   a     = 0000 1000

   b     = 0000 1001

   a^b = 0000 0001

bitwise negation (~) operator

Negation (Inversion) operator change the bit value to zero, if it is one and change the bit value to one if it is zero.

Example

a = 7

a in binary format is       0 0 0 0 0 1 1 1

~(a) in binary format is  1 1 1 1 1 0 0 0

~(a) represents -8 in binary format.

HelloWorld.groovy

a = 7

println "a : ${a}"
println "~a : ${~a}"

Output

a : 7

~a : -8
