How to "throw an exception?"

Hello, I wrote this code that takes values as input from a user until a negative number is entered, and then prints the average of those values, not including the negative number.
I need to figure out how to not print an average if the first number a user inputs is negative. I think I should "throw an exception," but I'm not really sure how to go about that.
Thanks!

Not really sure? Then since you want to know about exceptions, your google keywords should be "java exception tutorial".

The first link you get back should be Oracle's tutorial (have a look at the URL to make sure). Read it: Lesson: Exceptions.
 
I agree. Here's the link: http://aspose.com/file-tools
