        /* In brief -
        New - It refers to the stage of creating objects but not executing it. (i.e. Start() method is not called)
        ** as soon as start() is called it chooses thread, which are created in the new stage.

        Runnable - It gives the thread a position such that the thread scheduler chooses the thread to execute.

        Running - After a thread is selected it comes in stage of running.

        Non-Runnable - These Thread are runnable but wait for the correct instance ( For ex. While accessing a site a pdf viewer only works when we click on it)

        Termination - When the run() method exit it is called terminated.   */

              NEW = GET || RUNNABLE = SET || RUNNING = GO || NOT-ELIGIBLE = NON-RUNNABLE || FINISH = TERMINATED */
