| 1: | Why would you want to choose an Array object over an ArrayList object? Why would you choose an ArrayList object over an Array object? |
| A1: | An Array object has a set size, whereas an ArrayList object can grow as items are added to it. |
| 2: | The Array class internally allocates contiguous blocks of memory. Does the stack and queue do the same? Why or why not? |
| A2: | No, they don't. Stacks and queues are implemented more like linked lists than arrays. You cannot index a Stack or Queue object in the same way you can index an Array object. |
| 3: | What happens when you add a hash table element that has the same key to an element already in the hash table? |
| A3: | You will receive an ArgumentException. |
