NotFoundException

NotFoundException is a type of exception that is commonly encountered in programming, particularly in languages such as Java and C#. It is typically thrown when a requested resource, such as a file, database record, or web page, cannot be found. This exception is part of the broader category of exceptions known as runtime exceptions, which are usually thrown during the normal operation of a program.

In Java, NotFoundException is often used in the context of file handling. For example, if an application attempts to open a file that does not exist, a NotFoundException might be thrown. Similarly, in web development, a NotFoundException can be used to indicate that a requested URL does not correspond to any existing resource on the server.

In C#, the equivalent exception is often referred to as FileNotFoundException when dealing with file operations. This exception provides additional information, such as the name of the file that was not found, which can be useful for debugging purposes.

Handling NotFoundException involves implementing try-catch blocks in the code to catch and manage the exception gracefully. This can include logging the error, displaying a user-friendly message, or taking corrective actions such as prompting the user to provide a valid resource.

Overall, NotFoundException is a crucial part of error handling in programming, helping developers to manage scenarios where requested resources are unavailable, thereby improving the robustness and user experience of their applications.
