A list and some threads

9
Locked

Let's multiply threads again and again. In the main method, add five threads to the static list. Each thread must be a new Thread object that works with its own SpecialThread object. The SpecialThread class's run method should display "This is the run method inside SpecialThread".

can do it all in one simple line (tip...we don't need references to the Threads since they are in a list)

Why volatile?

so the List of threads wont be cached. Best practice, not specific to this task

The conditions are somewhat misleading since they give the impression the final code must display "This is the run method inside SpecialThread". Just ignore that condition, this shouldn't print anything to pass validation. I was also really confused by the two words "works with". I read that and had no idea what that meant. This is the first time I've seen that as a way of saying that one thing needs another thing as an argument.

A tip: You don't have to call Thread.start() method. 1) Create the object 2) Create a thread 3) Add thread to the list.

Deceptively difficult.

I didnt really get why I need to start the threads using the run() method and start() doesn't get through the valitadion. IntelliJ confused me even more stating "Calls to 'run()' should probably be replaced with 'start()'".

Confusing is a part of the learning process. Keep it up!
