I don't understand why?
Hey guys I have a question. I didn't quite understand why do I have to write the keyword new and the () in SpecialThread - - >> new Thread (new SpecialThread ()); Wouldn't be enough just address SpecialThread and nothing else? Or is it because it is a static class?

Requirements are met, data is randomly stored in each thread and displayed, yet not passing verification. Help pls!
If I introduce 3 and bing, bang, bong, the results are randomly stored in each list and they vary in storage every time. Yet it is not correct. Furthermore, if I introduce 0 or a negative number, the program terminates immediately. Therefore, what am I doing wrong?

Unable to find my "solution" field in IntelliJ IDEA
Hey all, Since I've switched from the web module to the InteliJ software I've been unable to see my solutions. Obviously this isn't a problem when you don't make mistakes.
