Question
Now that we've managed to weave our way through the North Woods safely and are one step closer to Thanto, our destination. After a night spent on the far side of the woods we wake up to the sound of rushing water. We quickly open our eyes and notice the Fraus River not 20 feet from where we lay. The river must have been expanding throughout the night in an attempt to swallow us whole. As we are standing on our ever shrinking piece of land we notice a homemade raft with a single passenger. After screaming and waving for a short amount of time we get the captain of this raft to paddle towards us.
After some quick deliberations the captain agrees that he can take us on his trip across the ever widening river. As always, there is a bit of a snag in our free ride. Our ride isn't exactly free, so we've got to do some work to earn the ride. What we need to do in order to earn our ride is increase the storage capacity and efficiency of our flower pack.
I have been adding features to the flower pack along the way:
Created a basic flower pack that can add, display and remove (using arrays)
Searched through the flower pack.
Sorted the flower pack.
Created a flower object to hold attributes of each flower.
Upgraded our flower pack (to now use an ArrayList)
Filter the flower pack based on a partial search.
Upgraded our flower pack (to now hold multiple different types of plants)
Saved and Loaded information to/from a file.
Create an interface for the user to display, add, remove, sort, and filter our flower pack.
Using recursion (no loops!) you must count the number of times a specific character, or set of characters appears in the name of each plant in your pack. We will call this 'analyzing' for the sake of future terminology.
In this case, we need to use a LinkedList for storing things in the flowerpack.
You must be able to display, add, remove, sort, filter, and analyze information from our flower pack.
Analysis Examples:
how you display the results is up to you
Analyze 3 different strings such as “ar”, “ne”, and “um” – which strings is up to you and does not require user input
Analysis can be case sensitive, if you so desire. Remember - you MUST use recursion to solve this problem. Meaning – not a single loop should be called when doing these calculations. You CAN use a loop when you want to move from analyzing one flower to the next, but your loop CANNOT be used when analyzing a specific flower.
The flower pack should hold flowers, weeds, fungus, and herbs. All should be a subclass of a plant class.
Each subclass shares certain qualities (ID, Name, and Color) – plant class
Flower traits include (Thorns, and Smell)
Fungus traits include (Poisonous)
Weed traits include (Poisonous, Edible and Medicinal)
Herb traits include (Flavor, Medicinal, Seasonal
Submit 7 files: Final.java, flower.java, fungus.java, plant.java, weed.java, herb.java and node.java
No GUI is required for this project.
Other answers I have seen did not used a linked list for storage, or include the node.java part. Please include those parts, thank you.
Let me know if you need more information, thank you.
