I am new to this language. What do I put in place of "aString" and how do I use the exception in my if statement? Add a throwsException to the end? Thanks.
Have a great day, Alex

If you're expecting an integer, then you can do
Integer.parseInt(aString)
That will throw a NumberFormatException if it isn't a number.
Take care, Sina

Hi all,Is there a quick way of determining if the user input is a
number? I need it
to be a number; it throws an exception and exits the program if
it isn't.
Maybe something like: if (input!=\intI have no idea about the syntax, but something along those lines
is what I
am looking for. Thanks for any help.
