Answer: The key differences between checked and unchecked exceptions are: 1. Exception Handling: Checked exceptions must be handled by the programmer during development using try-catch blocks or declaring the method as throws, while handling unchecked exceptions is optional. 2. Compilation Process: Checked exceptions are checked by the compiler, meaning the code won't compile if not handled, whereas unchecked exceptions don't affect the compilation process. 3. Error Prediction: Checked exceptions represent predictable and recoverable situations, while unchecked exceptions are typically caused by programming mistakes or unpredictable scenarios. 4. Inheritance: Checked exceptions are subclasses of 'java.lang.Exception' but not 'java.lang.RuntimeException', while unchecked exceptions are subclasses of either 'java.lang.RuntimeException' or 'java.lang.Error'. 5. Recommended Usage: Checked exceptions are preferred when the exception can be anticipated and recovered from, while unchecked exceptions are used for programming mistakes or unrecoverable errors.
