A

AbstractAnimal - Class in Unnamed Package: Abstract base class combining shared state, a concrete default method, and an abstract method subclasses must implement.
AbstractAnimal() - Constructor for class AbstractAnimal
age - Variable in class AbstractAnimal: Structural state isolated inside a class footprint (interfaces cannot hold this).
Animal - Class in Unnamed Package: Base class exposing an overridable speak() method.
Animal() - Constructor for class Animal

Cat - Class in Unnamed Package: Animal subclass that overrides speak() to meow.
Cat() - Constructor for class Cat

directSpeak(PureBreedDog) - Static method in class Part4_InterfaceMonomorphism: Scenario A: Monomorphic target explicitly declared by final type reference.
Dog - Class in Unnamed Package: Animal subclass that overrides speak() to bark.
Dog() - Constructor for class Dog
DogWithDefault - Class in Unnamed Package: Concrete AbstractAnimal that implements the required speak() method.
DogWithDefault() - Constructor for class DogWithDefault

InterfaceCat - Class in Unnamed Package: ISpeaker implementation that meows.
InterfaceCat() - Constructor for class InterfaceCat
InterfaceDog - Class in Unnamed Package: ISpeaker implementation that barks.
InterfaceDog() - Constructor for class InterfaceDog
ISingleSpeaker - Interface in Unnamed Package: Interface contract for a single, non-substitutable speaker.
ISpeaker - Interface in Unnamed Package: Interface contract for anything that can speak.

main(String[]) - Static method in class Part1_InheritancePolymorphism
main(String[]) - Static method in class Part2_InheritanceWithDefaults
main(String[]) - Static method in class Part3_InterfacePolymorphism
main(String[]) - Static method in class Part4_InterfaceMonomorphism
makeSleep(AbstractAnimal) - Static method in class Part2_InheritanceWithDefaults: Dynamic Dispatch using abstract parent reference.
makeSpeak(Animal) - Static method in class Part1_InheritancePolymorphism: Dynamic Dispatch via Class vtable.
makeSpeak(ISpeaker) - Static method in class Part3_InterfacePolymorphism: Contractual Dispatch via Dynamic itable Lookups.

Part1_InheritancePolymorphism - Class in Unnamed Package: Demonstrates inheritance-based polymorphism resolved via the JVM's per-class virtual method table (vtable).
Part1_InheritancePolymorphism() - Constructor for class Part1_InheritancePolymorphism
Part2_InheritanceWithDefaults - Class in Unnamed Package: Demonstrates inheritance-based polymorphism where a concrete default method is inherited unchanged alongside an abstract method that must be overridden.
Part2_InheritanceWithDefaults() - Constructor for class Part2_InheritanceWithDefaults
Part3_InterfacePolymorphism - Class in Unnamed Package: Demonstrates interface-based polymorphism resolved via the JVM's itable (interface method table) rather than a class vtable.
Part3_InterfacePolymorphism() - Constructor for class Part3_InterfacePolymorphism
Part4_InterfaceMonomorphism - Class in Unnamed Package: Demonstrates monomorphic dispatch: because PureBreedDog is final, the JIT can devirtualize the call and invoke speak() directly, without an itable/vtable lookup.
Part4_InterfaceMonomorphism() - Constructor for class Part4_InterfaceMonomorphism
PureBreedDog - Class in Unnamed Package: Sealed 'final' class ensures NO other subclass can modify this method path.
PureBreedDog() - Constructor for class PureBreedDog

sleep() - Method in class AbstractAnimal: A concrete default method, inherited as-is by all subclasses.
speak() - Method in class AbstractAnimal: Abstract method that subclasses must override.
speak() - Method in class Animal: Emits the generic animal sound.
speak() - Method in class Cat
speak() - Method in class Dog
speak() - Method in class DogWithDefault
speak() - Method in class InterfaceCat
speak() - Method in class InterfaceDog
speak() - Method in interface ISingleSpeaker
speak() - Method in interface ISpeaker: Emits this speaker's sound.
speak() - Method in class PureBreedDog
