Is there a wait function in kotlin? (I don't mean a Timer Schedule, but actually pause the execution). I have read that you can use Thread.sleep(). However, it doesn't work for me, because the function can't be found.
Answer
Thread sleep always takes a time how long to wait: https://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html#sleep(long)
public static void sleep(long millis)
throws InterruptedException
e.g.
Thread.sleep(1_000) // wait for 1 second
If you want to wait for some other Thread to wake you, maybe `Object#wait()' would be better
https://docs.oracle.com/javase/7/docs/api/java/lang/Object.html#wait()
public final void wait()
throws InterruptedException
Then another thread has to call yourObject#notifyAll()
e.g.
Thread1 and Thread2 shares an Object o = new Object()
Thread1: o.wait() // sleeps until interrupted or notified
Thread2: o.notifyAll() // wake up ALL waiting Threads of object o
