    Interrupt a Thread

    AjayL
      I am testing a small application to interrupt the new child thread created.

      My question is:

      How is t.interrupt() able to interrupt the child thread? Is t the main thread that creates a new child thread?
      So,shoudnt t.interrupt() interrupt the main thread rather than the child thread?
      or am I missing something?
      public class UsingFlagToShutdownThread extends Thread{
      
           private boolean running = true;
             
           // Entry point for a child thread.
           public void run() {
               while (running) {
                 System.out.print(".");
                 
                 try {
                   Thread.sleep(1000);
                 } catch (InterruptedException ex) {
                      Thread.currentThread().interrupt(); 
                     break;
      
                 }
               }
               
               System.out.println("Shutting down thread");
             }
             
           
             public static void main(String[] args)  throws InterruptedException {
             
                  UsingFlagToShutdownThread t = new UsingFlagToShutdownThread();
                  t.start();   // Create a Child Thread.
                  Thread.sleep(5000);
                  t.interrupt();    // How does t.interrupt() interrupt the child thread created?
             }
      
      }
