Executor Implementation

import java.util.concurrent.Executor;
class ExecutorExample1  implements Runnable,Executor 
{
	public void run(){
		System.out.println(Thread.currentThread().getName());
	}
	public void execute(Runnable r){
		Thread t1=new Thread(r);
		Thread t2=new Thread(r);
		t1.setName("t1");
		t2.setName("t2"); 
		t1.start();
		t2.start();
		
	}
	public static void main(String[] args) 
	{
		 ExecutorExample1 obj=new ExecutorExample1();
		 obj.execute(obj);
	}

I don't understand use of Executor.In both cases same output, then why will anyone implement this ?
