Question about the task Catching checked exceptions
Java Syntax, Level 9, Lesson 8
Resolved
Not sure what the issue is In the code the handleExceptions method is calling method1, method2 and method3. I am using one try catch block The catch statement is catching and printing what exceptions are caught. Therefore not sure what the actual issue could be that's causing the validation to fail Please advise.

Why am I getting all these exception errors?I feel like I've solved the task as far as I can, but I'm not sure why I'm getting all these exception errors. I'm guessing it has something to do with either my loop never ending, or the fact that it can't handle parsing empty fields or something when it runs out of numbers. Any ideas?
