12. What can you say about the below implement G front rear a. Dequeuing is slow, enqueuing is quick b. Dequeuing is quick, enqueuing is slow c. Dequeuing and enqueuing are equally efficient d. It is not possible to perform a dequeue operation in this implementation 13. What will happen with newElem in the below figure? front newElem rear newElem a. It will be enqueued to q b. It will replace the reference to rear c. It will be collected by the Java garbage collector d. It will be dequeued from q -T4. Which of the following statements is false? a. A constructor must have the same name as its class b. A constructor can be called multiple times (even after the instance of a class is created) c. A constructor is not explicitly called, it is automatically called when an instance of a class is created. d. A constructor must have a minimum number of formal parameters, as set in the class definition. 15. Which of the following statements is false? a. A class can have only one direct parent in Java b. Polymorphism allows to have different implementations of the same function for different subclasses c. Inheritance leads to reducing duplication in the code d. Inheritance and polymorphism are mutually exclusive (one of them can be applied in the implementation of a class and its subclasses, not both at the same time)
