We were thinking of using a try/catch block to make sure that the enemy car could be created using a URL. if the URL is invalid then we don't want the program to execute. However, I was reading about exceptions and it says that you cannot declare a variable in a try/catch because it's scope is only within the block. So when I tried to call the enemyCar constructor and pass in variables including the URL, it left the scope of the rest of the program. Where else could I put the try catch block to check for this error?
