Bitwise ‘AND’ (‘&’) is used to check if a specific permission is present, and bitwise NOT (‘~’) is used in combination with AND to revoke permission (WRITE, in this case). Difference Between Enum and Macro We use enums and macros for different purposes in C programming. Enums ...
In this article, we’ll explore multiple approaches to creating an unsigned long in Java, including using BigInteger, the ULong class from the jOOU library, and bitwise operations. Create Unsigned Long in Java Using the BigInteger Class The BigInteger class in Java is found in the java.math pa...
Bitwise XOR Bitwise operators are used in OpenCV so that we can extract or filter out the part of an image, portraying the image and operating with non-rectangular ROIs (Region of Interest). Use Bitwise AND Operator on Images in OpenCV In OpenCV, the Bitwise AND operator is used to combin...

Note that if you don’t bind (or attach a variable name) to the setTImeout, you can’t make use of the clearTimeout. In addition, if you pass the wrong identifier, you will not get an error, and the timeout will still exist....
7. Bitwise Operators A bitwise operatormanipulates individual bitsof its operands. Java defines several bitwise operators, which can be applied to the integer types,long,int,short,char, andbyte. 8. Ternary Operator Java has one conditional operator. It is called a ternary operator as it takesthr...
