When i run this program i can see one thread created by me and another one is the "main" thread.When i call t.start()m my thread starts.In the docs for start they gave as

The result is that two threads are running concurrently: the current thread (which returns from the call to the start method) and the other thread (which executes its run method).

In the above my new thread is current thread.Please say me the other thread which executes the run method


class NewThread implements Runnable {
Thread t;
NewThread() {
// Create a new, second thread
t = new Thread(this, "Demo Thread");
System.out.println("Child thread: " + t);
t.start(); // Start the thread
// This is the entry point for the second thread.
public void run() {
try {
for(int i = 5; i > 0; i--) {
System.out.println("Child Thread: " + i);
} catch (InterruptedException e) {
System.out.println("Child interrupted.");
System.out.println("Exiting child thread.");
class thread {
public static void main(String args[]) {
NewThread j=new NewThread(); // create a new thread
try {
for(int i = 5; i > 0; i--) {

System.out.println("Main Thread: " + i);
} catch (InterruptedException e) {
System.out.println("Main thread interrupted.");
System.out.println("Main thread exiting.");

Let's continue the discussion in this duplicate thread in the Threads forum, where it is a better fit.
