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

Bitwise operations are represented by functions that can be called in infix form. They can be applied only to Int and Long.

for example:

val x = (1 shl 2) and 0x000FF000

Here is the complete list of bitwise operations:

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
