You have been tasked to design a COVID-19 screening application for your campus. The guards at each gate will screen the students and enter their details on the application. The capabilities and features of the application should include a choice between the following functions: 1. A screening survey which will allow guards to record the students’ screening data. 2. Searching for a student’s details and status. Technical Requirements: 1. The application should make use of Parallel arrays that will hold the details of the student as it is entered along with their status (admitted/not admitted). No more than 300 students will be allowed on a campus at any given day and time. 2. No student should be allowed access to the campus after 12h00 in the afternoons regardless of whether capacity has been reached or not. 3. If a student’s temperature is 38 degrees or more, they will not be allowed entry into the campus.
What is heap. Create maximum heap using built in function or using array list. Use any one method for creation max heap.

The organisation you work for has asked you to create an interactive application that will assist with the allocation of employees to a cell phone network provider and phone number generation. You are required to prompt a user for three employee names which will randomly assign the employee to either the Vodacom, MTN or Cell C network. The employees also require a randomly generated phone number. The start of each phone number will begin with the following, depending on the network provider:
Create a class named Course_Details that will contain get and set methods for the course name,
student numbers and lecturer. In the Course_Details class include a method called Assign Venue
that will randomly generate a Venue/Class for the course. Venues can be from 1 to 3 only. Your
main class must include a static method to handle the printing of the course report.

A login JFrame Form:use NetBeans application
Functions:
1. Add a Book to the list with the given book id from a JTextField.
2.Display the image of a book cover with the given book id from a JTextField.
Create 5 sample “book cover” image files (in jpeg format) in your Project folder. An example is shown below:
You can create your own simple image files using a Paint program.
The file name for book-1 is Book1Cover.jpg, for book-2 is Book2Cover.jpg, and so on.
3. List the books (book title and short description) with respect to the given author name from a JTextField.
4. List the books (book title) with respect to the given category from a JTextField.
5. List the books (book title) with respect to the given category from a JTextField, sorted by their rating.
6. Display the number of books that the user has finished reading in the given year from a JTextField.
(with GUI) developed with Java programming language.
Create a project named “FavoriteBooks” which keeps a list of the books that a user has read and liked.
This list is stored in a text document (.txt) file and for each book it keeps the following data separated by a comma (,):Book id, Title, Category, First Author Name and Surname, Award Winner, Rating, Year, Number of Pages, and Short Description.
A login JFrame Form:
Functions:

3. Display the information of a book with the book title given fully or as a keyword from a JTextField..
Note: How you design the GUI (Graphical User Interface) of your project is optional.
