/**
* This program has no try/catch block and requires
* the use of "throw" to compile.
*
* THINGS TO TRY
* Compile and run this file and see what happens when
* you enter the name of a file that has 5 integers in it.
* Then, run it and enter the name of a non-existent file.
* Then delete the "throws" and recompile it and see
* what happens.
