## 07 May Java Bitwise Operators

Java Bitwise Operator operates on individual bits of the operands. Let us learn about the type of bitwise operators in Java.

Here, our example will have three variables,

1 2 3 |
int a = 6; int b = 7; int res; |

## Bitwise NOT

The Bitwise NOT operator inverts all the bits of its operand.

**Symbol**

1 |
~ |

**Example**

Let’s say a = 6, then

1 2 3 |
int a = 6; int res = ~a; System.out.println(res); |

**Output**

The output is 1,

1 |
1 |

Showing the above, with bits and the same result is visible,

## Bitwise AND

The Bitwise AND operator gives 1, if both the operands are 1.

**Symbol**

1 |
& |

**Example**

1 2 3 4 |
int a = 6; int b = 7; int res = a & b; System.out.println(res); |

**Output**

The output is 6,

1 |
6 |

Showing the above, with bits and the same result is visible,

## Bitwise OR

The Bitwise OR operator gives 1, if either of the bit is 1.

**Symbol**

1 |
| |

**Example**

1 2 3 4 |
int a = 6; int b = 7; int res = a | b; System.out.println(res); |

**Output**

The output is 7,

1 |
7 |

Showing the above, with bits and the same result is visible,

## Bitwise X-OR

The Bitwise X-OR operator gives 1, if exactly one operand is 1.

**Symbol**

1 |
^ |

**Example**

1 2 3 4 |
int a = 6; int b = 7; int res = a^b; System.out.println(res); |

**Output**

The output is 1,

1 |
1 |

Showing the above, with bits and the same result is visible,

## Bitwise Right Shift Operator

The Bitwise Right Shift operator shifts bit to the right specified number of times.

**Symbol**

1 |
>> |

**Example**

1 2 3 |
int a = 6; int res = a>>1; System.out.println(res); |

**Output**

The output is 3,

1 |
3 |

Showing the above, with bits and the same result is visible. It shifts once,

## Bitwise Right Shift Phil Zero Operator/ Unsigned Right Shift

The Bitwise Right Shift Zero operator does not preserve sign of original number and fills the new place with zero,

**Symbol**

1 |
>>> |

**Example**

1 2 3 |
int a = 6; int res = a>>>2; System.out.println(res); |

**Output**

The output is 1,

1 |
1 |

## Bitwise Left Shift Operator

The Bitwise Left Shift operator shifts the bit to the left specified number of times in the bit sequence.

**Symbol**

1 |
<< |

**Example**

1 2 3 |
int a = 6; int res = a<<1; System.out.println(res); |

**Output**

The output is 4,

1 |
4 |

Showing the above, with bits and the same result is visible. It shifts once,

## Bitwise AND Assignment

The Bitwise AND Assignment operator performs Bitwise AND and assigns the result to the variable. The Bitwise AND operator gives 1, if both the operands are 1.

**Example**

1 2 3 4 |
int a = 6; int b = 7; a|= b System.out.println(a); |

**Output**

The output is 7,

1 |
7 |

## Bitwise OR Assignment

The Bitwise OR Assignment operator performs a Bitwise OR and assigns the result to the variable. The Bitwise OR operator gives 1, if either of the bit is 1.

**Example**

1 2 3 4 |
int a = 6; int b = 7; a | = b; System.out.println(a); |

**Output**

The value of the result is in the variable a. The output is 7,

1 |
7 |

## Bitwise X-OR Assignment

The Bitwise X-OR Assignment operator performs Bitwise X-OR and assigns the result to the variable. The Bitwise X-OR operator gives 1, if exactly one operand is 1.

**Example**

1 2 3 4 |
int a = 6; int b = 7; a^ = b; System.out.println(a); |

**Output**

The value of the result is in the variable a. The output is 2,

1 |
2 |

## Right Shift Assignment

The Bitwise Right Shift Assignment operator performs Bitwise Right Shift and assigns the result to the variable. The Bitwise Right Shift operator shifts bit to the right specified number of times.

**Example**

1 2 3 |
int a = 6; a>> = 1; System.out.println(a); |

**Output**

The value of the result is in the variable a. The output is 3,

1 |
3 |

## Right Shift Phil Zero Assignment

The Bitwise Right Shift Phil Zero Assignment operator performs right shift phil zero and assigns the result to the variable.

The Bitwise Right Shift Zero operator does not preserve sign of original number and fills the new place with zero,

**Example**

1 2 3 |
int a = 6; a>>> = 2; System.out.println(a); |

**Output**

The value of the result is in the variable a. It shifts twice.

The output is 1,

1 |
1 |

## Left Shift Assignment

The Bitwise Left Shift Assignment operator performs Bitwise Left Shift and assigns the result to the variable.

The Bitwise Left Shift operator shifts the bit to the left specified number of times in the bit sequence.

**Example**

1 2 3 |
int a = 6; a<< = 1; // equivalent to a = a<<1 System.out.println(a); |

**Output**

The value of the result is in the variable a.

The output is 4,

1 |
4 |
