Java: Checked vs Unchecked Exceptions
Answer
They highlight programming errors. Frame the concept in practical terms so you can explain it during interview discussion.
Unchecked exceptions often indicate a violation of an API's contract, such as passing null to a method that doesn't accept it. These exceptions are not enforced at compile-time, leaving it to the developer to ensure correct usage. For example, calling a method with a null argument that doesn't expect it can lead to a `NullPointerException`.
