Which method of creating threads is better?

Java: “implements Runnable” vs. “extends Thread”

When should you use:

    class MyThread extends Thread {
    public void run() {
        System.out.println("Important job running in MyThread");
    }

    public void run(String s) {
        System.out.println("String in run is " + s);
    }
}

over:

    class MyRunnable implements Runnable {
    public void run() {
        System.out.println("Important job running in MyRunnable");
    }
}

Obviously we instantiate these differently but is there any difference once they are created?

Thread is a class that implements Runnable interface. Essentially, that means that this is allowable:

Runnable runnable = new MyThread();
runnable.run();

By implementing a Runnable, you're essentially have to implement the run() method for the Thread to execute it.

Other than that, I don't know what you're really asking.

-1, [`Thread`](http://docs.oracle.com/javase/7/docs/api/java/lang/Thread.html) is not an abstract class and your example code is really confusing (`run()` vs. `start()`). – Tomasz Nurkiewicz May 16 '12 at 21:50
Sorry, I did edit my post...and no....`Runnable` class has only the `run()` method. – Buhake Sindi May 16 '12 at 21:50
@TheEliteGentleman `Runnable` is not a class :) – Eng.Fouad May 16 '12 at 21:53
@Eng.Fouad, I didn't say that `Runnable` is a class. I said that `Thread` is a class that **implements** `Runnable`. Read properly. :-) – Buhake Sindi May 16 '12 at 21:55
`Runnable class has only the run() method` ;) – Eng.Fouad May 16 '12 at 21:56
Ooops...I can't re-edit my comment....just a mistake. – Buhake Sindi May 16 '12 at 21:57
