3. Yielding

yield() make the currently running thread head back to runnable to allow other threads to get their turn. 

A thread can be moved out of the virtual CPU by yielding. 

A thread that has yielded goes into the Ready state. 

The yield() method is a static method of the Thread class. 
It always causes the currently executing thread to yield.


class MyThread extends Thread {
  public MyThread() {
    setDaemon(true);
  }

  public void run() {

    for (int i = 1; i <= 10; i++) {
      System.out.println("Counting: " + i);
    }
  }
}

public class MainClass {
  public static void main(String[] argv) {
    MyThread ct = new MyThread();
    ct.start();
    Thread.yield();

  }
}
