   • A. In the order they are defined
   • B. In reverse order of definition
   • C. Randomly
   • D. Based on the severity of the exception

3. 15. What happens if an exception is caught by a `catch` block?

   • A. The program continues execution after the `catch` block
   • B. The program terminates
   • C. The `finally` block is skipped
   • D. The exception is re-thrown automatically

4. 16. What is the purpose of the `finally` block?

   • A. To handle the exception
   • B. To define the code that might throw an exception
   • C. To ensure that certain code is always executed
   • D. To declare a new exception

5. 17. If an exception occurs in the `try` block and is caught by a `catch` block, is the `finally` block executed?

   • A. Yes
   • B. No
   • C. Only if the exception is handled successfully
   • D. Only if the exception is unchecked

6. 18. Can a `try` block be nested within another `try` block?

   • B. No
   • C. Only if there is a corresponding `catch` block
   • D. Only if the outer `try` has a `finally` block

7. 19. Can a `try-catch` block be nested within a `finally` block?

   • A. Yes
   • B. No
   • C. Only if the `finally` block might throw an exception
   • D. Only in specific scenarios

8. 20. What is exception propagation?

   • A. The process of an exception being passed up the call stack if it is not caught in the current method
   • B. The process of handling multiple exceptions in a single `catch` block
   • C. The process of throwing a new exception from a `catch` block
   • D. The process of ignoring an exception

9. 21. What happens if a method declares that it `throws` a checked exception, but the calling code does not handle it?

   • A. The program terminates
   • B. The compiler will issue an error
   • C. The exception is ignored
   • D. The `finally` block is executed

10. 22. What is the purpose of creating custom exceptions in Java?

    • A. To handle standard exceptions in a specific way
    • B. To provide more specific information about errors that can occur in an application
    • C. To make the code more complex
    • D. To replace built-in exception classes

11. 23. How do you create a custom checked exception in Java?

    • A. By extending the `RuntimeException` class
    • B. By extending the `Error` class
    • C. By extending the `Exception` class
    • D. By implementing the `Throwable` interface

12. 24. How do you create a custom unchecked exception in Java?

    • A. By extending the `Exception` class
    • B. By extending the `Error` class
    • C. By extending the `RuntimeException` class
    • D. By implementing the `Throwable` interface
