Thread's 'getId()' Problem

Question

Hello All,
I try to use the ID of threads withoud any success.
I declare two threads in this way:
Thread threads[] = new Thread[2];
threads[0] = new Thread();
threads[1] = new Thread();
for(int i=0;i<2;i++)
  threads.start();
then, when I look for its ID's, I get for both '1' (is it the 'main' ID?)
// from the method which the thread has activated
System.out.printf("Thread's ID is: %d",Thread.currentThread().getId());Is there any way to change the ID of a thread?
Thanks :)

I try to implement Peterson Algorithm (which uses the threads' ID)
I extended 'Thread' class, here's 'start()'
  public void start()
         int i=0;
          while (i<5)
          {     counter.inc();     
               i++;
    }I have a shared counter for both threads. (I have a constructor which handle it)
class Counter
     long value=0;
                      Peterson lock = new Peterson();
     public void inc(){
          lock.lock();
          try{
                    long temp;
          temp = value+1;
          value = temp;
          } finally{
          lock.unlock();}
}and the 'lock()' code:
public void lock(){
          int i = (int) Thread.currentThread().getId();
          System.out.println(i);
          int j = 1-i;
          flag[i] = true;
          victim = i;
          while (flag[j] && victim==i){}; // WAIT HERE
     }Probably you are right, because I get '1' in 'System.out.printf(i)'.
