**Checked Exceptions**

Checked exceptions are a type of exception in programming languages like Java that are checked at compile-time. These exceptions must be either caught using a try-catch block or declared in the method signature with a throws clause. They are typically used to represent recoverable conditions and enforce error handling, ensuring that the programmer explicitly deals with potential problems such as file I/O errors or invalid user input. Understanding checked exceptions is essential for writing robust and reliable code.
