There are two ways I know of to create Threads.

1.

    Thread thread = new Thread()
    {
     @Override
     public void run()
     {
      //do something;
     }
    };

  1.  Thread thread = new Thread(new Runnable()
 {
  @Override
  public void run()
  {
   //do something;
  }
 });

What I am asking is that, are there any differences in these methods, like which one is more efficient regarding Memory usage, CPU usage (if there is any difference), etc.

    basically, your question is: should I extend Thread, or should I implement Runnable. Unless you plan on altering default behavior of the Thread class (which in about 99% you really don't want to do) do NOT extend Thread, always go for an implementation of Runnable. – Stultuske Jun 25 '20 at 05:18
  • No it doesn't answer my question! – Miles Morales Jun 25 '20 at 05:21
  • Please read it properly. Moreover, both are same just you are using an interface and class. – Anish B. Jun 25 '20 at 05:22

    @PeterParker it should, actually. you are asking the difference between an anonymous class extending Thread, and an anonymous class implementing Runnable, that link is exactly what you should read. – Stultuske Jun 25 '20 at 05:27
  • The memory and CPU usage will be exactly the same (maybe a difference of a few bytes on the memory side, but it is completely insignificant compared to the size of the JVM for example). Use the second construct, it's cleaner. – assylias Jun 25 '20 at 05:28

    These days (Java 8 and later), `new Thread(() -> { /*do something*/ })` would be better. Or the *method reference* equivalent. Both saves the creation of an anonymous class. – Andreas Jun 25 '20 at 05:35
  • @Dioxin Both are anonymous classes. – Andreas Jun 25 '20 at 05:38
  • What does this 1uestion have to do with swing? Please remove the swing tag. – NomadMaker Jun 25 '20 at 05:39
