Question 21 Not yet In a linked-node implementation of a ADT, node does not reference the data in another node answered Points out of 2.00 Select one: True P Flag question False

Answer 1

21 - FALSE

23 - TRUE

25 - Yes, Node should be a public class . A Node provides a generic node for a linked list. Each node contains a piece of data (which is a reference to an object) and a link (which is a reference to the next node of the list). The reference stored in a node can be null. So, if it is not public we cannot create a Node class as it cannot be accessed publicly.

26 - clear() method only clears all the element from the list and not deletes the list.

The simplest and shortest method to implement the clear() method is - list.clear();

27 - (c) It avoids moving data when adding or removing bag entries.

28 - (a) at a rondom place. (we can insert it at anywherein the list)

29 - (b) inner class

30 - (a) all options are valid
