Thread t = Thread.currentThread();
System.out.println("Current thread: " + t);
// change the name of the thread
t.setName("My Thread");
System.out.println("After name change: " + t);
try {
for (int n = 5; n > 0; n--) {
System.out.println(n);
Thread.sleep(1000);
}
} catch (InterruptedException e) {
System.out.println("Main thread interrupted");

Notes:
-
When Java program runs. It calls the main thread because it is the first thread that starts running when a program begins.
- Thread.currentThread() will give the reference to Main Thread.
- Main thread of program executes when your program begins.
- Main Thread is a parent thread of every thread.
- From Main Thread other “child” threads will be spawned.
- Main thread is the thread to finish execution last, because it performs various shutdown actions.
