java - Switch/When without break in Kotlin -

this question has answer here:

• “when” statement vs java “switch” statement 7 answers

i'm new kotlin , want switch don't have 'break'. in java that:

    switch (b){         case 3:             log.d("int", "3");         case 2:             log.d("int", "2");         case 1:             log.d("int", "1");     } 

and if b = 2 print:

d/int: 2

d/int: 1

i want in kotlin without repeting same code each case. in kotlin convertor, code output that:

when (b) {   3 -> {     log.d("int", "3")     log.d("int", "2")     log.d("int", "1")   }   2 -> {     log.d("int", "2")     log.d("int", "1")   }   1 -> log.d("int", "1") } 

is there way of doing that? actual code way bigger that;

what you're asking "fall-through", not supported in kotlin. actually, it's not design use imho of course depends on use case.

if want it, can extract code blocks executed in cases in (local) functions if like:

fun fallthrough(myint: int) {      fun case3() = println("1")      fun case2() {         case3()         println("2")     }      fun case1() {         case2()         println("3")     }      when (myint) {         3 -> case1()         2 -> case2()         1 -> case3()     } }
