Java 1.8 Lambda & Method Reference

One way to create thread is to pass a object that implements Runnable Interface to a Thread constructor as mentioned in Java Multithreading Approaches (Java Concurrency - Part 1):

​public class MyRunnable implements Runnable{
  // this method is called when a runnable thread starts
  public void run(){
    printMessage();
  }
}

public class ThreadDemo{
  public static void main(String args[]){
    Thread t1 = new Thread(new MyRunnable); 
    Thread t2 = new Thread(new MyRunnable);
    Thread t3 = new Thread(new MyRunnable);
    t1.start();    
    t2.start();
    t3.start();
  }

  public static void printMessage(){
    System.out.println("Hello");
  }
}
