Naming :: Threads

I find it a good habit to name the threads that we create. For example, in Java the name of the Thread that executes the main method is called 'main'.

It's very useful while debugging or while viewing our log files when we have the thread namea in the log messages. It's especially useful in a multi-threaded application.

public class Main {
  public static void main(String[] args) {
    // Let's see the main thread's name.
    System.out.println("We are currently in: "
           + Thread.currentThread().getName());
  
    Thread thread = new Thread() {
      public void run() {
        String currentThreadName = Thread.currentThread().getName();
    
        for (int i = 0; i < 5; i++) {
          // Printing the user thread's name.
          System.out.println("We are currently in: "
              + currentThreadName);
        }
      }
    };
  
    // Setting a name for our user thread.
    thread.setName("MyUserThread");
    thread.start();
  
    // We're back in the main thread, let's check it.
    System.out.println("We are currently in: "
         + Thread.currentThread().getName());
  }
}

So, let's all give our Threads a meaningful name :-)
