11.8.2. Inner Classes

Try these first

1. 1.

   What is an inner class?

   Hint

   Think about how inner classes can organize related information.

2. 2.

   Can a static inner class access non-static members of the outer class?

   Hint

   Consider if instance members are accessible without creating an instance.

3. 3.

   What is the main purpose of inner classes?

   • To extend base classes
   • To logically group related classes
   • To implement interfaces

   Hint

   Think about how inner classes keep related code organized.

4. 4.

   True or False: A static inner class can directly access non-static members of the outer class.

   • True
   • False

   Hint

   Consider how static members work in relation to instances.

5. 5.

   Create a simple Java application that has a Library outer class and an inner class for Book. The Book class should include attributes like title and author, and methods to display them, including how they relate to the Library.

   Hint

   Consider how the Book class represents items within the Library.

6. 6.

   Discuss an instance when using an inner class might complicate the code unnecessarily. Provide an example.

   Hint

   Think about scenarios where the inner class doesn’t add logical or functional value.
