I had a 30-minute chat with a recruiter.

Next, I was called for an on-site, one-hour interview where I was asked general questions about Java, JVM, concurrency, and more.

Following that, I was asked to take the "King test," which involved about 10 hours of programming at home.

I was then invited for a code review. The interviewers pointed out errors in my code in a friendly enough manner. I felt I was able to justify my mistakes, and they seemed to accept my corrections.

The next morning, I was simply told, "We've decided not to move forward with the process." I never received any further explanation when I asked for feedback or the reason behind their decision.

What do the parameters in HttpServer.create(...) mean?

Are exceptions really necessary, or is it just better to pass on error codes?
