从Groovy 1.0 beta 10开始，Groovy支持位运算：<<. >>, >>>, |, &, ^, and ~.
下表列出了位运算的操作符和其含义：
|
Operator Symbol |
Meaning |
|
<< |
Bitwise Left Shift Operator |
|
>> |

|
>>> |

|
| |
Bitwise Or Operator |
|
& |
Bitwise And Operator |
|
^ |
Bitwise Xor Operator |
|
~ |
Bitwise Negation Operator |
|
<<= |
Bitwise Left Shift Assign Operator |
|
>>= |

小例子：
1 |
assert (1 << 2) == 4 // bitwise left shift
|
2 |
assert (4 >> 1) == 2 // bitwise right shift
|
3 |
assert (15 >>> 1) == 7 // bitwise unsigned right shift
|
4 |
assert (3 | 6) == 7 // bitwise or
|
5 |
assert (3 & 6) == 2 // bitwise and
|
6 |
assert (3 ^ 6) == 5 // bitwise xor
|
7 |
int mostlyOnes = 0xFFFFFFFE
|
8 |
assert ~mostlyOnes == 1 // bitwise negation
