RE: quick java question

You put in a variable that is of type string. That is, if you have a string
which you think has an integer in it, such as "24 dogs", but I believe, from
later posts, that you're looking for a double, so I'll await the code.

Take care,

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
