How to create a custom Exception class

Question

I'm confused about this in part 4 of the study guide: "Creating & throwing a custom Exception subclass." How do you do this? Are there any resources on moodle for this? Thanks!

Answer 1

All you have to do is create a new class and give it an exception name that has the word "Exception" in it and make that class extend the Exception class or the RuntimeException class.

Answer 2

For better example, you could take a look at the .java files (LowAccountBalanceException.java and BankAccount.java) uploaded on Moodle during week October 31 - November 6 for better example of how to throw a custom Exception class in BankAccount.

Hope this helps!

Answer 3

Create a class and extend the Exception class. Create the new exception and give it your own message to throw or get the message from the Exception class.
