9:31 As we know that super and this should be the first statement in any constructor and when we try to use both it will contradict and give error. But why does it compile here?

how are you able to call the method eat(); without initializing the animal class since eat(); is a public method and we need to create an instance to call it. Am I missing something. ref: line no. 10 @ 4:49
