Yes. We can call run() method of a thread. But it does not work as a

separate thread. It will just work as a normal object in main thread

and there will not be context switching between the threads.

class CustomThread extends Thread {
 
public void run() {
  for (int i = 0; i < 5; i++) {
   try {
    Thread.sleep(300);
   } catch (InterruptedException e) {
 
    e.printStackTrace();
   }
   System.out.println("Thread is running :"+i);
  }
 
}
 
}
 
public class StartThreadAgainMain {
 
public static void main(String[] args) {
  CustomThread ct1 = new CustomThread();
  CustomThread ct2 = new CustomThread();
  ct1.run();
  ct2.run();
 
}
 
}
