Hi! I really need help with:

4.2 Write the Java code to declare a new class Bee which is a subclass of Insect. The noise made by a Bee is "Buzz".

4.3 Write the Java code to declare a new abstract class Amphibian that implements the MakesNoise interface.

4.4 Write the Java code to declare a new class Frog which is a subclass of Amphibian. The noise made by a Frog is "Ribbet".

4.5 Modify the run() method of Main and add some Bees and Frogs to critters.

6.2 Explain how a local class differs from an inner class.

6.3 Explain how an anonymous class differs from an inner and local class.

Thank you!
