Q1 Inhertiance21 PointsGrading comment:

For each of the following, tell if the code will compile. If so, what will be be printed? If not, why will it not compile?

Give a one sentence reasoning for EITHER outcome. (No reasoning gets max 1 point.) Note: Syntax errors, if any, are inadvertent and should be ignored. Also, code outside of an explicit class is considered to be in the main method of some arbitrary class in the same package. (Fields that are not private are accessible to all classes in same package.)
