Write a Program in java to show Multithreading.

classNewThread implements Runnable

                {

                Thread t;

                NewThread() {

               

                t = new Thread(this, "Demo Thread");

                System.out.println("Child thread: " + t);

                t.start(); // Start the thread

                }

               

                public void run()

                {

                try {

                for(int i = 5; i > 0; i--)

                 {

                System.out.println("Child Thread: " + i);

                Thread.sleep(500);

                }

                }

                catch (InterruptedException e) {

                System.out.println("Child interrupted.");

                }

                System.out.println("Exiting child thread.");

                }

                }

                classThreadDemo

               {

                public static void main(String args[ ] )

                 {

                newNewThread();

                try

                {

                for(int i = 5; i > 0; i--)

                {

                System.out.println("Main Thread: " + i);

                Thread.sleep(1000);

                }

                } catch (InterruptedException e) {

                System.out.println("Main thread interrupted.");

                }

                System.out.println("Main thread exiting.");
