Given the following class definition: public class Car { private String vehicleld; public Car (String vehicleid) { vehicleld = this.vehicleId; } What is wrong with it? (Select all that apply) The assignment overwrites the parameter value The class should be marked as abstract The constructor is missing its return type The instance variable vechicleld should be public

Question
QUESTION 7 Assume a Pet class contains a declaration for a method called getName () that returns a String. Later, we do this: public class Dog extends Pet{ ... How would we go about overriding this method in the new class? O We can only override this method if it is abstract in the Pet class O We must declare a method in the new class with the same method name and parameter list O We must first use the super () constructor to ensure that the name has a value We must declare a method in the new class with the same method name and return type QUESTION 8 Consider a linked list of nodes containing integer values. What it the run time associated with searching for a specific value in the list? O 0(1), because we can always access a specific node with an index O O(n), where n is the size of the list O(log n), if the list is in sorted order The length of the list is undefined, therefore the run time cannot be determined QUESTION 9 Given the following class definition: public class Car { private String vehicleId; public Car (String vehicleId) { vehicleld = this.vehicleId; } What is wrong with it? (Select all that apply) | The assignment overwrites the parameter value The class should be marked as abstract O The constructor is missing its return type The instance variable vechicleld should be public
