What are checked and unchecked exceptions in Java? Provide examples of each.
- Checked exceptions: These are exceptions that are checked at compile-time. They must be either caught using a try-catch block or declared using the "throws" keyword. Example:
IOException. - Unchecked exceptions: These exceptions are not checked at compile-time and are subclasses of
RuntimeException. They do not need to be caught or declared. Example:NullPointerException
