Kotlin by Example: Values

Kotlin has various types including strings, integers, floats, booleans, etc. Here are a few basic examples.

fun main() {

Strings, which can be added together with +.

    println("kot" + "lin")

Integers and floats.

    println(1 + 1)
    println(7.0 / 3.0)

Booleans, with boolean operators as you’d expect.

    println(true && false)
    println(true || false)
    println(!true)
}
