Java Programming: Lesson 71 (OLD, SEE DESCRIPTION)

PLEASE SUBSCRIBE!!!

THIS VIDEO HAS BEEN REPLACED BY https://youtu.be/JeSLpMim15M BUT YOU CAN CONTINUE TO WATCH THE VIDEO AND READ THE DESCRIPTION FOR THIS VIDEO IF YOU'D LIKE

In the previous lesson (https://youtu.be/Vr9ZVFrb4zk), we discussed pass-by-value, in which Java passes a copy of a variable into the static method rather than a literal reference to the variable itself. In this video we review 3 solutions:
1. use an instance variable instead of a local variable
2. return a value instead of simply updating it
3. use an array instead of a local variable

In this video, we do more review of advanced data structures. Altogether we have:
2 ArrayLists (ArrayList, Vector)
1 LinkedList
1 Stack
2 Queues (Queue, ConcurrentLinkedQueue)
2 Sets (HashSet, LinkedHashSet)
4 Dictionaries (HashMap, Hashtable, LinkedHashMap, ConcurrentHashMap)

The more important takeaway in this video is to be able to compare and contrast iterators, list iterators (https://youtu.be/Irwh9qSlPAw), and enumerations (https://youtu.be/4jHQuaMOnOU). How do you use each, and which are available to each of the 12 data structures we discussed in 12 different videos? (28, 51, 52, 53, 54, 55, 59, 64, 66, 67, 68, 69)
