Kotlin has a predefined set of operators with fixed symbolic representation (such as +, and *) and fixed precedence. Most of the operators are translated directly into method calls; some are translated into more complex expressions. The following table contains a list of all the operators available in Kotlin:
Operator token |
Corresponding method/expression |
a + b |
a.plus(b) |
a - b |
a.minus(b) |
a * b |
a.times(b) |
a / b |
a.div(b) |
a % b |
a.rem(b) |
a..b |
a.rangeTo(b) |
a += b |
a.plusAssign(b) |
a -= b |
a.minusAssign(b) |
a *= b |
a.timesAssign(b) |
a /= b |
a.divAssign(b) |
a %= b |
a.remAssign(b) |
a++ |
a.inc() |
a-- |
a.dec() |
a in b |
b.contains(a) |
a !in b |
!b.contains(a) ... |
