How do I know, the thread is finished in Kotlin?-CodePudding

Im trying to set text after all threads are finished. Do you have any ideas for me?

fun threadStart(){
var ende = 150_000
val s = Semaphore(1)

var thread1 :Thread = Thread(Runnable{
    while(counter < ende){
        counter  
        println("1. Thread : $counter")
        println("${Thread.currentThread().name} 1. Thread  $counter")
    }
    if(counter == ende) {
        while (counter != 0) {
            counter--

            println("${Thread.currentThread().name} der Minus counter $counter")
            s.release()
        }
    }
thread1.start()
thread2.start()
thread3.start()
thread4.start()

Normally I would write a print after thread4 here or in the main after threadstart()

CodePudding user response：

Are you asking how to make the main thread wait for the other threads to finish? If so, you can do that with:

thread1.join()
thread2.join()
thread3.join()
thread4.join()
