Bitwise Logical Operators(位运算符)由于在一般的日常开发当中很少涉及,所以在《Thinking in java》,《Core Java 2》等Java书籍中只是略有提及,一笔带过。 也没找到一本参考书对其有详细描述,兴趣所致,在网上搜索了许多资料。终于大致了解了其原理。 位运算符包括:~,|,&,^ ~ the NOT Operator (非运算符) |...
Logical operators compare Boolean expressions and return a Boolean result. The And, Or, AndAlso, OrElse, and Xor operators are binary because they take two operands, while the Not operator is unary because it takes a single operand. Some of these operators can also perform bitwise logical ...

5. Difference Between Bitwise and Logical Operators There are a few differences between the bitwise operators we’ve discussed here and the more commonly known logical operators. First, logical operators work on boolean expressions and return boolean values (either true or false), whereas bitwise ...
Bitwise vs. Logical Operators Earlier, we mentioned that there are bitwiseandlogical versions of the various boolean operators (e.g., norgate). When using vectors, the distinction between the two operator types becomes important. A bitwise operation between two N-bit vectors replicates the operatio...

Microsoft had planned to change the behavior of the words to function only as logical operators, and it planned to add new operators for bitwise operations. Carol Sliwa, Computerworld, 9 Apr. 2001 It speeds up parity-bit generation and parity checking by performing bit-wise XOR operations on ...
New bitmasks can be created by using the bitwise logical operators on these primitive bitmasks. For example, the bitmask 1011 can be created by ORing FLAG_A, FLAG_B, and FLAG_D: var mask = FLAG_A | FLAG_B | FLAG_D; // 0001 | 0010 | 1000 => 1011 ...
Logical Operators Relational Operators Assignment Operators Bitwise Operators Misc Operators All the Bitwise operators work at the individual bit level. The bitwise operator can only be applied to the integer and character data types. For example, if you have an integer type variable with the size ...
The similarities between bitwise and logical operators go beyond that.It’s possible to evaluate Boolean expressions with bitwise operators instead of logical operators, but such overuse is generally discouraged. If you’re interested in the details, then you can expand the box below to find out ...
