```
public class Test extends Thread{
    public void hello(String s){
        System.out.println(s);
    }
    public void run(){
        hello("I’mrunning...");
    }//endofrun()
    public static void main(String [] args){
        Test t=new Test();
    System.out.println("always first");
        t.start();

        System.out.println("always second but why?");
    } 
} 

```

I've run that chunk of code 30 times. 

Why is "always second but why?" always second on the console? When t.start() is called, we have 2 threads. (2 stacks): the main thread and the second thread. so "i'am running" has to be sometimes the second output on the console. When i delete the "always first" output statement than the two outputs left, behave non deterministic (that's the way it should be) 

so what is wrong in my thinking, why is System.out.println("always first"); influencing the concurrency?
