New name to 'main' thread

Question

Hi All,
I tried to change the name of the main thread with the following code:
class TT{
static public void main(String [] args){
MyRunnable r = new MyRunnable();
Thread.currentThread().setName("newmain"); //new name given to main thread
System.out.println("Thread :"+Thread.currentThread().getName());
Thread t1 = new Thread(r,"a");
Thread t2= new Thread(r,"b");
Thread t3 = new Thread(r,"c");
t1.start();
t2.start();
t3.start();
class MyRunnable implements Runnable{
public void run(){
System.out.println("Current Thread is"+Thread.currentThread());
try{
Thread.sleep(100);} catch(InterruptedException e){}
}The output show something like this ->
Thread :*newmain*
Current Thread isThread[a,5,*main*]
Current Thread isThread[b,5,*main*]
Current Thread isThread[c,5,*main*]
What I am trying to ask here is: In the last three lines newmain_ should have appeared in place of main_ . Because I changed the name of the main() thread. Am I right??

class TT{
static public void main(String [] args){
MyRunnable r = new MyRunnable();
Thread.currentThread().setName("newmain"); //new name given to main thread
System.out.println("Thread :"+Thread.currentThread().getName());
Thread t1 = new Thread(r,"a");
Thread t2= new Thread(r,"b");
Thread t3 = new Thread(r,"c");
t1.start();
t2.start();
t3.start();
class MyRunnable implements Runnable{
public void run(){
System.out.println("Current Thread is"+Thread.currentThread());
try{
Thread.sleep(100);} catch(InterruptedException e){}
}Hi..
You have created 3 different threads from main thread with name a,b and c. In run() you are printing the current thread not name so the result. If you print name, you will get the name as a,b,c not newmain...
