Original question:

I need a program that simulates a flower pack with the traits listed below:

- You must use a LinkedList for storage (not an Arrray list).

- You must be able to display, add, remove, sort, filter, and analyze information from our flower pack.

- 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)

No GUI is required.

The code I have is listed below, it appears to do just about everything I need it to. I would like you to take a look and see if the analysis part of the program is done correctly according to the instructions.

Here are the instructions regarding analyzing information from our flower pack:

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.

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

Please let me know if it is done correctly, or what the code should look like if it needs work, thank you.

Here is the code I have:
