![]() ![]() This is also known as an inclusive OR operation. When used, for each bit in the resulting number, it will be a 1 if either bits in the operands are 1’s or if both of them are 1’s, and it’s a 0 otherwise. The OR operator will perform a bitwise OR operation on two numbers. int number = 13 īoolean isEven = (number & 1) = 0 // Result: falseĮxample of a Java class that demonstrates the use of the bitwise AND operator to determine if a number is even or odd. If the result is 0, then the number is even. One example where you might use the bitwise AND operator is when you are trying to find the parity of a number (whether it is even or odd). ![]() The bitwise AND operator will perform the AND operation on each corresponding pair of bits: This means that for each bit in the resulting number, it will only be a 1 if both of the bits in the operands are 1’s, and a 0 otherwise. The AND operator will perform a bitwise AND operation on two numbers. This normally allows you to represent numbers up to 2,147,483,647 (when one bit is used as the sign bit, indicating if it is positive or negative.) For the purposes of this article, however, we will mostly use numbers that can be represented as 8 bits. For example, an integer in Java is 32 bits. Even though most of the details are abstracted away, this principle carries over to Java.ĭata is represented as a certain number of bits, or binary digits. Bit ReviewĪs you likely know, a computer operates on electrical signals, and the presence or absence of electricity is often represented as binary, or base two. You may wish to leverage this for a number of reasons, but first, let’s review what bits are. So, let’s get into it! What are Bitwise Operators?īitwise operators allow a programmer to act on data at the bit level, making it possible to extract or manipulate specific bits. There are multiple bitwise operators to consider, but they are all rather simple.Īlthough bitwise operators are not often necessary, it’s important for you to understand them if you want to have a solid grasp of Java programming. Understanding the bitwise operator in Java can prove helpful in numerous situations, especially when dealing with lower-level operations. ![]()
