Q.13 Write an application that creates and start three threads, each thread is instantiated from the same
class. It executes a loop with 5 iterations. First thread display “BEST”, second thread display “OF” and
last thread display “LUCK”. All threads sleep for 1000 ms. The application waits for all threads to
complete and display a message.
Solution :-Â
class MessageThread extends Thread {
private String message;
public MessageThread(String message) {
this.message = message;
}
public void run() {
try {
for (int i = 0; i < 5; i++) {
System.out.println(message);
Thread.sleep(1000);
}
} catch (InterruptedException e) {
System.out.println("Thread interrupted: " + e.getMessage());
}
}
}
public class ThreadExample {
public static void main(String[] args) {
MessageThread t1 = new MessageThread("BEST");
MessageThread t2 = new MessageThread("OF");
MessageThread t3 = new MessageThread("LUCK");
t1.start();
t2.start();
t3.start();
try {
t1.join();
t2.join();
t3.join();
} catch (InterruptedException e) {
System.out.println("Main thread interrupted: " + e.getMessage());
}
System.out.println("All threads have completed execution.");
}
}
