// BogusExceptionDemo.java

// Creates a new exception subclasss called DemoException,
// derived from superclass Exception.  Shows an exception specification 
// (aka: "throw list"), try block, throw statement, and catch block ("handler").
// In the catch block, 
// When the exception is caught, method printStackTrace() is called for 
// the DemoException object parameter bogus, and then the program continues.
// Note that there is no DemoException constructor.  Since no argument is 
// supplied when a DemoException object is created, Java will synthesize a
// default constructor.
