You want that internship? You better know POLYMORPHISM. Sit DOWN.
This is a dog. Dogs make sounds. What sound? Correct.
Gold star. This is a cat. Cats ALSO make sounds.
What sound? DIFFERENT sound. Same ACTION. Stay with me. In code,
I don't wanna write 'makeBarkSound()' and 'makeMeowSound()' like some KIND OF ANIMAL. I just write
'makeSound()' for BOTH. The parent class says 'hey, all animals make sounds.' But EACH
animal does it differently. That's polymorphism, baby! New animal?
Just add it! Duck.makeSound() equals QUACK! Same function name, new behavior! ONE interface.
