// Threads allows a program to doing multiple things at the same time.

// It can be created by extending the Thread class and overriding its run() method.

// Another way to create a thread is to implement the Runnable interface.

// The major difference is that when a class extends the Thread class, you cannot extend any other class, but by implementing the Runnable interface, it is possible to extend from another class as well

// Example extending the Thread

// public class Ex21Thread extends Thread {

// public static void main(String[] args){

// Ex21Thread creatingThread = new Ex21Thread();

// creatingThread.start();

// System.out.println("Thread start, but this code is running outside the thread");

// }

// public void run(){

// System.out.println("This code is running in a thread");

// }

// }

// Example implement the Thread interface

public class Ex21Thread implements Runnable {

public static void main(String[] arg){

Ex21Thread threadObj = new Ex21Thread();

Thread creatingThread = new Thread(threadObj);

creatingThread.start();

System.out.println("Thread start, but this code is running outside the thread");

}

public void run(){

System.out.println("This code is running in a thread");

}

}
