Interruptions

Here's a class Worker that extends Thread.

class Worker extends Thread {
    
    @Override
    public void run() {
        String msg = "It was interrupted";     // 1
        
        try {
            Thread.sleep(200);                 // 2
        } catch (InterruptedException e) {
            System.out.println(msg);
        }
        
        int i = 0;                             // 3
        while (i < 100_000) {
            if (isInterrupted()) {
                System.out.println(msg);
                return;
            }                      
            i++;                               // 4
        }
        
        System.out.println("Finished");        // 5
    }
}

Another thread calls the interrupt method of this thread. The Worker thread will print "It was interrupted" if another thread interrupts it during...
