Question
After dinner with Alexander and Elizabeth we notice that Alexander is mixing some herbs as a medication for Elizabeth which eases her pain and helps her sleep. Once the medicine is administered we begin small talk with Alexander. During the conversation he tells us the story about how his mother and father were hopelessly in love and were lucky enough to die side by side protecting the things they loved most, their children. In the middle of the story we become distracted by Elizabeth trying to request something, but we can't make out what she wants because her medicine has kicked in. After a few moments we determine she is requesting a flower, but we can't understand the entire name, just the start. Instantly we remember that we know how to search through our flower pack while only using partial names. We instantly turn around and start working on yet another improvement to the flower pack. • Create a flower object that has specific traits (name, color, presence of thorns and smell) • These flower objects must be able to stay in his pack (Use an ArrayList) • Be able to add and remove flowers • Implement a partial search (Searching for 'r' should return all flowers with an 'r' in their name, and the same goes for any partial search). This is commonly known as a filter. As a new addition a rubric has been added to blackboard for the assignment. Using the same code as assignment 2 you can make your changes. I have included some base code for your convenience (This has 2 classes: Assignment3 and Flower). Submit 2 files: Assignment3.java and Flower.java import java.util.ArrayList; import java.util.Scanner; public class Assignment3 { public static void main(String[] args) { new Assignment3(); } // This will act as our program switchboard public Assignment3() { Scanner input = new Scanner(System.in); ArrayList flowerPack = new ArrayList(); System.out.println("Welcome to my flower pack interface."); System.out.println("Please select a number from the options below"); System.out.println(""); while (true) { // Give the user a list of their options System.out.println("1: Add an item to the pack."); System.out.println("2: Remove an item from the pack."); System.out.println("3: Search for a flower."); System.out.println("4: Display the flowers in the pack."); System.out.println("5: Filter flower pack by incomplete name"); System.out.println("0: Exit the flower pack interface."); // Get the user input int userChoice = input.nextInt(); switch (userChoice) { case 1: addFlower(flowerPack); break; case 2: removeFlower(flowerPack); break; case 3: searchFlowers(flowerPack); break; case 4: displayFlowers(flowerPack); break; case 5: filterFlowers(flowerPack); break; case 0: System.out .println("Thank you for using the flower pack interface.

I am using textpad to code it.
Explanation / Answer
There is no big problem in your code. Your code is not able to convert object type into Flower type inside methods
Flower tmp = itr.next();
In this line. You just need to typecast it as
Flower tmp = (Flower)itr.next();
Below is the complete working code
