Your code looks fine, you are missing a "c" in your Exception. Fix that spelling error and you should be good.
Happy coding and welcome to Treehouse!

function someFunction() throws SomeException {
throw new SomeException();
}

Treehouse TeacherHi James,
Not yet ;) I used a RuntimeException on purpose, they do not need to be defined. More to come soon!

Spelling can indeed drive one nuts. Great work on getting the concept though, that is an important step. Remember that during the challenges you can take a look in the Preview section and, generally, get error messages. With the code you posted above you get a cannot find symbol error with the caret pointing to IllegalArgumentExeption.
The cannot find symbol error is Java's way of saying "I don't know what that is!" I wrote a bit about that error in this post. You might take a look just for your reference. As you will discover, learning what the error messages are indicating can help greatly in the debugging process.
Happy coding and pleased that it worked out.
