java - 如何在 Kotlin 中使用 Java 的位运算符？

Question

Java 有 binary-or | 和 binary-and & 运算符:

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

它们似乎不适用于 Kotlin:

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

如何在 Kotlin 中使用 Java 的位运算符？

Answer 1

您已经为它们命名了函数。

直接来自 Kotlin docs

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

例如:

val x = (1 shl 2) and 0x000FF000

这里是按位运算的完整列表:

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
