public class MyRunnable implements Runnable { @Override public void run() { // This method runs in a separate thread try { // Some long-running operation for (int i = 0; i < 5; i++) { System.out.println("Running in thread: " + Thread.currentThread().getName()); Thread.sleep(1000); // Sleep for a second } } catch (InterruptedException e) { // Common mistake: Not handling InterruptedException correctly System.err.println("Thread was interrupted!"); } } public static void main(String[] args) { // Common mistake: Not starting the thread properly MyRunnable myRunnable = new MyRunnable(); Thread thread = new Thread(myRunnable); // Starting the thread thread.start(); // Common mistake: Not checking if the thread has finished running try { thread.join(); // Wait for the thread to finish } catch (InterruptedException e) { System.err.println("Main thread was interrupted!"); } System.out.println("Main thread finished."); } }
