// Thread.getName()  gets the current threads name from 0....to...
// Thread.setName("new name")---> setName(String name)--> set name for the thread
// Thread.currentThread() gets the current thread object || is used with getName()
// Thread.currentThread().getName()-->gets the name of thread executing currently
// thread scheduler : used for setting priority to threads 
// Thread.MIN_PRIORITY -->1
// Thread.MAX_PRIORITY --> 10
// Thread.NORM_PRIORITY -->5
// t1.setPriority(5);
// t1.setPriority(Thread.NORM_PRIORITY)-->5;
// default priority for every thread 5
// child threads derives priority from the parent main thread--5

*  Thread.sleep(2000) delays till time and then executes.
