It extends `IllegalArgumentException`. You can create it with no message or with a custom detail message. Key methods from its inheritance, `Throwable`, include managing the exception's cause, getting its message, accessing the stack trace, adding or retrieving suppressed exceptions, and printing the stack trace. `Integer.parseInt(String)` is an example of where it can be thrown.\n"]]
