    import java.util.concurrent.ThreadFactory;  
      
    public class ExecutordefaultThreadFactoryExample1 {  
       
        public static void main(String[] args) {  
            ThreadFactory thrdfctry = Executors.defaultThreadFactory();  
            Thread t = thrdfctry.newThread(new Mythrd());  
            t.start();        
        }   
    }  
      
    class Mythrd implements Runnable {  
       
        @Override  
        public void run() {

    import java.util.concurrent.ThreadFactory;  
      
    public class ExecutordefaultThreadFactoryExample2 {  
       
        public static void main(String[] args) {  
            ThreadFactory thrdfctry = Executors.defaultThreadFactory(); 
            for(int i=0 ; i<=5 ; i++){
            Thread t = thrdfctry.newThread(new Mythrd2());  
             t.start();        
        }   
    }  
    }
    class Mythrd2 implements Runnable {  
       
        @Override  
        public void run() {  
            System.out.println("Running thread concurrently  ::" +  new Date());
