   What is a checked exception?

   Hint

   Think about how Java handles exceptions at compile time.

2. 2.

   Name one limitation of lambda expressions.

   Hint

   Consider exception handling mechanisms.

3. 3.

   Can lambda expressions throw checked exceptions directly?

   • True
   • False

   Hint

   Think about how you handle exceptions in Java.

4. 4.

   Which is a common limitation of lambda expressions?

   • They are always clearer than named classes.
   • They cannot have multiple statements.
   • They cannot throw checked exceptions directly.
   • They are always more concise.

   Hint

   Recall the rules regarding exceptions in Java.

5. 5.

   Create a lambda expression that attempts to throw a checked exception and explain the resulting error.

   Hint

   Consider how Java expects checked exceptions to be managed.

6. 6.

   Design a real-world scenario where using a named class would significantly improve code readability compared to a lambda expression.

   Hint

   Think about complex functionalities and their representation.
