// ThreadExample.java

public class ThreadExample {

      public static void main(String[] args) {

            //creating first thread

            Thread t1 = new Thread(new Runnable() {

                  //to store seconds count

                  int seconds = 0;

                  @Override

                  public void run() {

                        //loops infinitely

                        while (true) {

                              //pausing the thread for 1 second

                              try {

                                    Thread.sleep(1000);

                              } catch (InterruptedException e) {

                                    e.printStackTrace();

                              }

                              //incrementing seconds passed

                              seconds++;

                              //displaying seconds passed

                              System.out.println("seconds passed: "+seconds);

                             

                        }

                  }

            });

            //creating second thread

            Thread t2 = new Thread(new Runnable() {

                  //to store 3 seconds count

                  int seconds = 0;

                  @Override

                  public void run() {

                        //loops infinitely

                        while (true) {

                              //pausing this thread for 3 seconds

                              try {

                                    Thread.sleep(3000);

                              } catch (InterruptedException e) {

                                    e.printStackTrace();

                              }

                              //incrementing count of 3 seconds

                              seconds++;

                              //displaying three seconds passed

                              System.out.println("\t\t\tthree seconds passed: "+seconds);

                             

                        }

                  }

            });

            //starting both threads

            t1.start();

            t2.start();

      }

}
