jvm - What is Unit Object in Kotlin -


this question has answer here:

right learning kotlin, in guide run these 2 methods, 1 withunit , 1 doesn't

method withunit

fun printsum(a: int, b: int): unit {   println("sum of $a , $b ${a + b}") }

method without unit

fun printsum(a: int, b: int) {   println("sum of $a , $b ${a + b}") }

my question is, unit actually? void in java? if it's void why 1 of method above doesn't have unit run fine.

which 1 should use when want method returning nothing? , when best time use unit.

anyone can explain? cause it's confusing me. in advance.

yes.it mentioned in website @ github source that

object unit type 1 value: unit object. type corresponds void type in java.

also in repository,

/** * type 1 value: unit object. type corresponds void type in java. */

when use it?
