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

Solution 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
andLong
.
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
Solution 2
you can do this in Kotlin
val a = 5 or 10;
val b = 5 and 10;
here list of operations that you can use
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

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;

xjcl over 3 yearsNote that bitwise inversion would be used like
5.inv()
, not as infix like the others -
grian over 3 yearsNote that bitwise inversion is also known as bitwise complement or bitwise NOT

Hakanai almost 3 yearsI find it odd that Kotlin decided bitwise operators would get these awkwardly named functions, while the actual boolean operators like and and or still got operators. It's a bit backwards isn't it? If anything I'd want these to stay as the symbols and the boolean operators to become words.
