Runnable a thread?

Question

Is a class that implements Runnable itself a thread?
When i invoke run() method of a class that implements Runnable does it behave like a thread?
Or only Runnable object wrapped by Thread class is a Thread?

Answer 1

Is a class that implements Runnable itself a thread?Implementing Runnable is another way of writing threads, if you implement runnable you dont need to extend Thread, as a matter of fact it is considered the better way for writing threads. But thats another discussion

use start
class PrimeRun implements Runnable {
         long minPrime;
         PrimeRun(long minPrime) {
             this.minPrime = minPrime;
         public void run() {
             // compute primes larger than minPrime
PrimeRun p = new PrimeRun(143);
     new Thread(p).start();
