Not meeting condition 5 So I am trying to solve this task and it says on condition 5 to make sure it works correctly for negative numbers, but under my logic it should not give any issues. What's wrong then??

Why don't we need to start new thread?b) void run() - It should get a SocketThread object via the getSocketThread() method and call its run() method. Figure out we don't need to call the run() method on a separate thread, like we did for the console-based client. Why do we call run instead of start? Thank you

IntelliJ Timeout issues On some of the task through the IntelliJ plugin, especially when they call for user input, I'm getting a lot of timeout errors even though the code compiles fine in the IDE. There are a few tasks that I can't even verify because of this issue. Anyone else experiencing this? Any ideas or solutions?

I've tried doing already completed tasks in the past and they don't allow me to attempt them again. Best ways to get back into the swing of things?
