Using Interface and Polymorphism in Java Program

Using Interface and Polymorphism in Java Program

JAVA CODE:

//1.  Implements the runnable() interface

//Here interface is used by implementing the runnable at the class

public class threade implements Runnable

       {

        

       //2.  Implements the run() method of the runnable() interface to do the following:

//overriding through an Interface was used By implements the method run() with the runnable()

          

       public void run() {

              

       ////Note: The Thread.currentThread().getName() method is helpful for retrieving thread names.

              

       System.out.println(Thread.currentThread().getName()+ "running");

            

       //a.  Count down, starting with the number 5 and going to 0

       int i = 5;      

       while (i >= 0) {

                  

       ////b.  Print the name of the thread and the current value of countdown integer

                  

       //for each integer counted down

          //here polymorphism is used        

       System.out.println(Thread.currentThread().getName()+": "+i--);

               }

              

       //c.  Print "Blast Off!" when 0 is reached in the countdown

              

       System.out.println("Blast Off!");

           }  

       public static void main (String[] args)

         //Overriding - same method names with same arguments and same return types associated in a class and its subclass.

       //Overloading - same method name with different arguments, may or may not be same return type written in the same class itself.

       {

       //3.  Creates five threads in your main class giving each thread a name:

              

       //"Thread 1", "Thread 2", "Thread 3", "Thread 4", and "Thread 5"

          

       Thread thread1 = new Thread(new threade());

          

       thread1.setName("Thread 1");

          

       Thread thread2 = new Thread(new threade());

          

       thread2.setName("Thread 2");

          

       Thread thread3 = new Thread(new threade());

          

       thread3.setName("Thread 3");

          

       Thread thread4 = new Thread(new threade());

          

       thread4.setName("Thread 4");

          

       Thread thread5 = new Thread(new threade());

          

       thread5.setName("Thread 5");

          

       ////4.  Starts all five threads

          

       thread1.start();

          

       thread2.start();

          

       thread3.start();

          

       thread4.start();

          

       thread5.start();

         }

       }
