Scala: How do I know that there were unhandled exceptions before starting the program?

Question

this is a test program:

object Test {

    def main(args: Array[String]): Unit = {
        // there is an unhandled exception in here, I expect program can remind me, and I can handled it before running.
        myException()  
    }

    def myException: Unit ={
        throw new Exception
    }
}

In Java, when I call a method with an exceptional exception, an error will occur in the program and will tell you add throws declarationor surround with try/catch.

How do I know if a program has unhandled exceptions before running in Scala ?
