An Exception class, which contains several types of methods, is also provided by Ruby as a separate class for an exception. Because the code that raises an exception is wrapped between the begin/end blocks, you can use a rescue clause to address it.
You can use the rescue block to catch an exception and then use the retry statement to restart the begin block.
Raise a specified exception that will be caught by the controller. An error number that the view interprets to an error message might be included in the exception.
As a method return parameter, return an error code.
Create a @error (or whatever) instance variable that the caller can inspect.
First, we're throwing an exception, which we can throw if the code encounters a scenario where it can't continue to execute. Simply said, it will cause a problem and prevent continued execution.
Exception assignments are important for organizations to make sure that they have a clear understanding of the exceptions that need to be handled. They also help in making sure that the work is distributed evenly among the team members.
