Program for implementing Runnable interface

There are two ways to create a thread:

1. By extending Thread class
2. By implementing Runnable interface.

This program demonstrates you how to use the second mechanism for creating threads by implementing Runnable interface. The steps for creating a thread by using the second mechanism are:

1. Create a subclass that implements the interface Runnable and override run( ) method:

   class MyThread implements Runnable {
   
    // Overrride run( ) method with "public" access specifier
    public void run( ) {
     // Thread body of execution
    }
   }

2. Create an object

   MyThread t1 = new MyThread( );

3. Creating Thread object

   Thread t = new Thread( t1 );

4. Start Execution of created thread by calling start( ) method:

   t.start( );

PROGRAM

class ImpementingRunnable implements Runnable {

 @Override
 public void run() {
  
  System.out.println("This thread is running ... ");
 }

 public static void main(String[] args) {
  
  Thread t = new Thread(new ImpementingRunnable());
  t.start();
 }
}

OUTPUT

C:\>javac ImpementingRunnable.java
C:\>java ImpementingRunnable
This thread is running ...
