BufferedReader throws IOException, which is a checked exception. Checked exceptions are checked by the compiler at compile time and must be handled either by try catch or by throwing the exception up the callstack to a point at which it is handled. Since this is used in the main method and not handled via a try catch it is thrown up to the JVM where it is handled. Omitting either results in the error. https://www.tutorialspoint.com/java/java_exceptions.htm#:~:text=An%20exception%20(or%20exceptional%20event,exceptions%20are%20to%20be%20handled.
