A tiger is a bit more than a cat. And a cat is a pet. And in turn, any pet is an animal. And all of them descend from Object. Something is wrong with the inheritance in our program. Correct the 'Object animal = new Pet();' line in the main method so that the program displays "Bingo!"

A rose by any other name: it's no coincidence that the famous cartoon cat is called Tom. In the language of Shakespeare, a tomcat is a male cat. Obviously, tomcat is also a "regular" cat and can move. Correct the program so that the variable cat references an object that simultaneously implements CanMove, and is a Cat and a Tomcat.
