Exercise 1 – Iterative vs. recursive methods 1. Create a new project called Lab9 and copy the given .java files into the src folder of this lab project folder. Refresh the project in Eclipse to show the provided files there. 2. Open FibonacciDemo.java and FactorialDemo.java and examine the code. Carefully read through the ifib() and rfib() methods in FibonacciDemo and ifact() and rfact() in FactorialDemo. Compare the iterative and recursive approaches in both classes. Why do the iterative method
(Characters around Circle) Write a program that displays a string “Welcome to Java” around the circle, as shown in Figure 14.44b (Book). Hint: You need to display each character in the right location with appropriate rotation using a loop. Sample output: Please submit the following: 1. The entire project folder containing your entire project ( That includes .java file) as a compressed file. (zip) 2. Program output−screenshot Also, 1. Copy and paste source code to this document underneath the lin
Create a Java program A shopping lists. This could be done as a linked list of nodes where each node has its own child linked list of store options (Linked list of linked lists) as follows: Develop a program to simulate a mall consists of several stores, each store contains a group of items. Using the system you can add items to the shopping kart, remove them, edit their data, and confirm purchase according to the following rules: 1- Every store specializes in a specific type of items that is
For this lab, you will implement a simple To Do List application. The program must include a GUI that looks like this: ToDos must provide the following features: Adding items: To add a new item: Click the “New Item” button, at which point all of the input fields clear Enter the following fields: Item – Required field – Cannot be blank – Must be unique — there must not exist another item with this name Priority – Required field – Cannot be blank – Must be an integer > 0 – Items with a lower prio
Directions: Using best practises in programming, design and develop a project based on the following requirements: 1. Ask the user how many words they would like to type 2. Let the user input the words 3. Print the words one by one with their respective frequencies 4. Ask the user if they want to repeat. If they say yes, repeat the steps. If not, end the program. • Assume the program only allows up to 20 words • The program may read the number of words and words all in the same line or separat
Directions: Using best practises in programming, design and develop a project based on the following requirements: 1. Upon running the program, it should welcome the user to your Ice Cream shop and assign them a random order number. (randomly generated by the system.) 2. Next, it should ask the user if they want ice cream on a cone or cup. 3. Ask them for the number of scoops. Limit the maximum number of scoops to three. 4. Ask them for the flavour of the ice cream for each scoop they selected.
