Follow these steps to implement the example:

1. Create a class called PrimeGenerator that extends the Thread class:

        public class PrimeGenerator extends Thread{

2. Override the run() method including a loop that will run indefinitely. In this loop, process consecutive numbers beginning from one. For each number, calculate whether it's a prime number; if yes, as in this case, write it to the console:

        @Override 
        public void run() { 
          long number=1L; 
          while (true) { 
            if (isPrime(number)) { 
              System.out.printf("Number %d is Prime
",number); 
            }

3. After processing a number, check whether the thread has been interrupted by calling the isInterrupted() method. If this method returns true, the thread has been interrupted. In this case, we write a message in the console and end the execution of the thread:

            if (isInterrupted()) { 
              System.out.printf("The Prime Generator has been
                                 Interrupted"); 
              return; 
            } 
            number++; 
          } 
        }

4. Implement the isPrime() method. You can get its code from the Creating, running, and setting information of a thread recipe of this chapter.
5. Now implement the main class of the example by implementing a class called Main and the main() method:

        public class Main { 
          public static void main(String[] args) {

6. Create and start an object of the PrimeGenerator class:

        Thread task=new PrimeGenerator(); 
        task.start();

7. Wait for 5 seconds and interrupt the PrimeGenerator thread:

        try { 
          Thread.sleep(5000); 
        } catch (InterruptedException e) { 
          e.printStackTrace(); 
        } 
        task.interrupt();

8. Then, write information related to the status of the interrupted thread. The output of this piece of code will depend on whether the thread ends its execution before or after:

          System.out.printf("Main: Status of the Thread: %s
",
                            task.getState()); 
          System.out.printf("Main: isInterrupted: %s
",
                            task.isInterrupted()); 
          System.out.printf("Main: isAlive: %s
", task.isAlive()); 
        }

9. Run the example and see the results.
