How to print all exceptions thrown by some Scala program?

Are Scala Exceptions stored in some global exceptions table or a similar kind of a structure and if so is there any way to access it other than catch?I mean if I need to print all exceptions thrown by some Scala program what is the best way to do so?

Thanks

There is no table where the exceptions are stored as far as I know. You can add an unhandled exception catcher for a given thread, the same way you do that in Java:

  import java.lang.Thread.UncaughtExceptionHandler
  import java.security.InvalidKeyException

  Thread.setDefaultUncaughtExceptionHandler(new UncaughtExceptionHandler {
    override def uncaughtException(t: Thread, e: Throwable): Unit = {
      println(e)
      println(e.getStackTrace.mkString("\r\n"))
    }
  })

But your exception should be unhandled in the thread for that to work. And if one unhandled exception happened - no other exceptions can be thrown - so I am not sure what do you mean by all exceptions
