Explanation / Answer

5) Reason for question 5 for not getting error is we are casting h to type House which is derived downcasting. So eventhough h is of type Habitable as we have casted that to house it will call the getSize() of class House class which was inherited to the USCDorm class. By casting it will be clear to the compiler which method to call so it will not cause compile error. As we have casted now compiler will look for getSize() inHouse class.

6) Reson for casing error in this class is we have not casted the reference variable P which is of type House eventhough it was holdingUSCDorm type. If we didnot cast it will look into House class for the temperature() but itwas not there in that class. Thats why it will give compile error.
