Java Programming 2-5: Collections Part 2 Practice Activities Lesson objectives: Implement a HashMap Implement a stack by using a deque Define a link list Define a queue Implement a comparable interface Vocabulary: Identify the vocabulary word for each definition below. A double-ended queue; a queue that can add and remove elements to the front or back of the list. The links of a LinkedList. An interface used to define a group of objects. This includes lists and sets. Maps that link a Key to a Value and may have duplicate Keys but cannot have duplicate Values. A list of elements that is dynamically stored A list of elements with a first in first out ordering. Try It/Solve it: 1. What is the difference between a Queue and a Stack? Give an example of each. 2. Is it possible to add nodes to the beginning of a LinkedList? If so, how? What about adding a node to the end of a LinkedList? If this can be done, what method would be used? 3. What is the purpose of implementing the Comparable interface in one of our classes
