Thread doesn't return control to main() after being interrupted, why?

Question

Hello,
From the following code you would expect control returned to main() after a thread is interrupted. But output shows otherwise. Why?
Thank you in advance for your help!
public class HelloRunnableInterruptB implements Runnable {
     public void run() {
          System.out.println("Hello from a thread!");
          while (true) {
               if (Thread.interrupted()) {
                    System.out.println("Interrupt received in infinite loop");
                    return;
     public static void main(String[] args) {
          HelloRunnableInterruptB threadObj = new HelloRunnableInterruptB();
          Thread thread1 = new Thread(threadObj);
          thread1.start();
          thread1.interrupt();
          System.out.println("main: 1st statement after interrupt()");
/*Output:
Hello from a thread!
Interrupt received in infinite loop
*/

From the following code you would expect control returned to main() after a thread is interrupted. But output shows otherwise. Why?No. It is giving result as expected. Thread dies when its run() method complete execution.
Moreover, when you call a start() method , the result is that two threads runs concurrently: the main thread and the other thread. They have two different lines of execution.
