Thread management

Here's a class that extends Thread and overrides the run method:

class MyThread : Thread() {
    override fun run() {
        println("Hello from $name")
    }
}

And a snippet of code:

fun main() {
    val t1 = MyThread()
    t1.name = "My-thread-1"
    t1.start()

    t1.join()

    val t2 = MyThread()
    t2.name = "My-thread-2"
    t2.start()
    println("output-1")
    t2.join()
    println("output-2")
}

In what order may the strings be printed out? Select all possible cases. Note that Output case: is not part of the output.
