(Note: while this is Scala application, I assume the behaviour would be the same for Java, hence the Java tag).Just completed a restaurant waitlist program using Java and I'm having some issues. handle uncaught exceptions in the debugger instead of being printed in the console.avoid the AWT thread restarting on exception, or at least prevent the popup from showing.To learn the working about the queue, visit Queue Data Structure.

When I am lucky enough to switch into the debugger (which is difficult, because more and more popups keep coming as the application gets paint requests), the debugging console shows me an exception information like: Moreover, the thread seems to be restarted, and as the exception is a result of coding error, it is shown again and again.
