This operator combines its two integer operands by performing a Boolean OR operation on their individual bits. The result has a bit set if the corresponding bit is set in either or both of the operands. It has a zero bit only where both corresponding operand bits are zero. For example: |...
The Java programming language also provides operators that perform bitwise and bit shift operations on integral types. The operators discussed in this section are less commonly used. Therefore, their coverage is brief; the intent is to simply make you aware that these operators exist. The unary ...
| Bitwise OR ^ Bitwise XOR ~ Bitwise complement Shift left >> Shift right Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the...

Both operands to the bitwise AND operator must have integral types. The usual arithmetic conversions covered inStandard conversionsare applied to the operands. Operator keyword for& C++ specifiesbitandas an alternative spelling for&. In C, the alternative spelling is provided as a macro in the <is...

Java Boolean Operators (Not-short-circuit) Boolean AND (&) When used with boolean operands, the&operator behaves like the&&operator, except that it always evaluates both operands, regardless of the value of the first operand. This operator is almost always used as a bitwise operator with intege...
In this article Syntax Remarks Operator keyword for & Example See also Syntax and-expression: equality-expression and-expression&equality-expression Remarks The bitwise AND operator (&) compares each bit of the first operand to the corresponding bit of the second operand. If both bits are...
In Java, this operation is straightforward, and we’ll see three different ways to achieve it. Additionally, we’ll discuss a corner case: integer overflow. For simplicity, we’ll use unit test assertions to verify the result of each approach. 3. Using the Unary Minus Operator The most str...
