Bitwise operators are useful for manipulating bit patterns in programming. They offer a quick and efficient way to perform complex operations (e.g. decryption of data, calculation of hashes, etc.) that require manipulating individual bits in a binary number. It is important to understand what the binary representation of different numbers looks like. For example, the binary representation of the number 12 is the “0b1100” and is the binary representation of 10 “0b1010”.

There are six bitwise operators in Kotlin: and, or, xor, inv, shl and shr, which are used to manipulate bit patterns. Here are examples of using these operators in Kotlin:

and Operator performs a bitwise AND operation between the operands and returns the result.

This example performs a bitwise AND operation between the binary numbers 1100 and 1010 executed what 1000 results.

or operator performs a bitwise OR operation between the operands and returns the result.

This example performs a bitwise OR operation between the binary numbers 1100 and 1010 executed what 1110 results.

xor operator performs a bitwise XOR operation between the operands and returns the result.

This example performs a bitwise XOR operation between the binary numbers 1100 and 1010 executed what 0110 results.

inv operator reverses the bit patterns of the operands and returns the result. For example:

In this example, the bit pattern of 1100 vice versa, what 0011 results.

shl operator Shifts the bits of an operand to the left by the specified number of positions and fills the free positions on the right with zeros. For example:

In this example, the bit pattern of 1100 shifted two places to the left, what 110000 results.

The SHR operator shr: The SHR operator shr shifts the bits of an operand to the right by the specified number of positions and fills the empty positions on the left side with zeros. For example:

In this example, the bit pattern of 1100 shifted two places to the right, what 0011 results.
