orElseThrowexc

orElseThrowexc is a method commonly found in optional types within various programming languages, particularly Java. Its primary purpose is to provide a concise way to handle situations where an optional value might be absent.

When an optional object contains a value, the orElseThrowexc method simply returns that value. However, if the optional object is empty, meaning it does not hold a value, the method throws a specified exception. This exception is typically provided as an argument to the method, often in the form of a supplier function that creates the exception instance.

This approach offers a more expressive and less verbose alternative to traditional null checks or manually throwing exceptions. Instead of writing a separate if-statement to check for emptiness and then throwing an exception, orElseThrowexc consolidates this logic into a single method call. It promotes clearer code by immediately indicating the expected outcome when an optional is empty. The ability to specify the exact exception to be thrown enhances error handling and debugging capabilities, allowing developers to provide context-specific error messages.
