What is the difference between Runnable and extends Thread

0 votes

There are 2 ways of writing Threads in Java:

public class myRunnable implements Runnable {
    public void run() {
        //Code
    }
}

Or, with extends Thread:

public class myThread extends Thread {
    public myThread() {
        super("myThread");
    }
    public void run() {
        //Code
    }
}

What are the significant differences in these two blocks of code?

Runnable is the preferred way to create a thread as it. You're not really specialising the thread's behaviour. You're just giving it something to run.

It means you can implement Runnable and extend from another class as well. while extending thread we cannot extend another class.
