Runtime Errors in Ruby

Exceptions in Ruby are unintended events that disrupt a program’s execution, necessitating proper handling to maintain the program's logic flow. Ruby uses a begin-end block structure, with a rescue block to manage exceptions, defaulting to a RuntimeError if no specific class is mentioned. This hierarchy places RuntimeError under StandardError, itself a subclass of Exception. Examples illustrate raising exceptions with messages and how specifying exception classes like ZeroDivisionError can aid in debugging by providing clarity and reducing complexity in larger codebases. Tools like Rollbar facilitate real-time error tracking and management, enhancing the reliability and confidence of deploying Ruby applications by simplifying the process of identifying and fixing errors.
