How do I use Java's bitwise operators in Kotlin?

Question

Java has binary-or | and binary-and & operators:

int a = 5 | 10;
int b = 5 & 10;

They do not seem to work in Kotlin:

val a = 5 | 10;
val b = 5 & 10;

How do I use Java's bitwise operators in Kotlin?

Answer 1

You have named functions for them.

Directly from Kotlin docs

As of bitwise operations, there're no special characters for them, but just named functions that can be called in infix form.

for example:

val x = (1 shl 2) and 0x000FF000

Here is the complete list of bitwise operations (available for Int and Long only):

shl(bits) – signed shift left (Java's <<)
shr(bits) – signed shift right (Java's >>)
ushr(bits) – unsigned shift right (Java's >>>)
and(bits) – bitwise and
or(bits) – bitwise or
xor(bits) – bitwise xor
inv() – bitwise inversion
