In this course project you need to compile the principles of object-oriented programming in order to design and implement a graphical user interface application using JavaFX. The application is a food ordering application, where the user login to the system using a given username and password and land to a main panel which shows the menu items of the available dishes, and the user selects the items that he/she wishes to order, and the application prints out a bill that shows the order details. The main features:
1. A given text file "USERS.txt" contains username, password pairs of the registered users in the system, where the application reads the file from the beginning and creates an object for each user.
a. Design a User class that contains the properties and methods of the users.
b. The application parses the USERS.txt file and converts its content into an array of users objects.
2. A given file "MENU.TXT" contains the details of the available dishes in the restaurant such as (type, price, imageName, calories ...etc).
a. Design a Dish class that contains the properties and methods related to the restaurant dish.
b. The imageName property associated with each dish will point to an image file that the application will show in the panel.
c. The app reads the file and creates the menu in a GUI allowing the users to select the items they wish to order. 3. The app calculates the total price of the selected items and exports the order bill into a file.
4. Before closing the app, the app exports the inventory showing all the orders that have been ordered during that session.

To make a shared directory read-only, you should add the "ro" option to the entry for that directory in the /etc/exports file. The "ro" option stands for "read-only" and restricts write access to the shared directory.

Here's an example of how the entry in the /etc/exports file might look like:

/path/to/shared/directory  client_IP(ro)

After making changes to the /etc/exports file, you need to restart or reload the NFS (Network File System) service for the changes to take effect. This can typically be done using the following command:

sudo systemctl restart nfs

It's recommended to use IPv6 as the IP addressing scheme because of its features and backward compatibility with IPv4.

In this case, the choice of the IP address standard depends on the number of hosts, scalability, and future expansion plans. Given that the law firm has just moved to a newly constructed building and there is consideration for future growth or expansion, it's recommended to use IPv6.

IPv6 was created to address the limitations of IPv4, which includes the depletion of IPv4 addresses because of the huge increase in the number of internet-connected devices. IPv6 uses a 128-bit addressing system compared to IPv4's 32-bit addressing system. This means that IPv6 can provide almost limitless IP addresses to the network.

IPv6 features include:

IPv6 also provides backward compatibility with IPv4, allowing for easy migration to the new protocol while still maintaining backward compatibility with IPv4 networks.

As a result, it's recommended to use IPv6 as the IP addressing scheme because of its features and backward compatibility with IPv4.

In internet of things (iot), information technology (it) can be distinguished from operational technology (ot) in the two ways: IT is based on queries and IT uses data at rest. So the options 1 and 3 are the correct answer.

On the other hand, operational technology (OT) typically focuses on managing and controlling physical processes and devices in industrial or operational settings. OT deals more with real-time data in motion rather than static data at rest.

By distinguishing IT in terms of query-based operations and working with data at rest, it highlights the difference between IT's focus on retrieving and processing stored information and OT's focus on real-time monitoring, control, and management of physical processes.

So the correct answers are option 1 and 3.

To obtain the minimal tie sets of a reliability network, one can use the cut-set method.

This method involves identifying all possible cut-sets in the network, which are the minimal sets of components that, if removed, would disconnect the network into two or more separate components.

The minimal tie sets can then be derived by complementing the cut-sets, which gives the sets of components that must be operational for the network to function. For example, consider a simple network consisting of three components A, B, and C connected in series.

The cut-sets of this network are AB and BC, as removing either of these sets would disconnect the network. Therefore, the minimal tie sets are AC (the complement of AB) and ABC (the complement of BC), which are the sets of components that must be operational for the network to function.

Finally, there are 3 computers in the collection that run both Windows and Linux. We need to determine how many computers in the collection run Windows but neither of the other two operating systems. The Windows-only computers comprise those computers that are only running Windows and those computers that are running both Windows and another operating system, but not Linux or Android. Only 3 computers are running Windows and Linux, so there are no computers running Windows and neither Linux nor Android.

An instance variable refers to the data value that is associated with a specific instance of a class.

In object-oriented programming, a class is a blueprint or template for creating objects, which are instances of that class. Each instance of a class can have its own set of instance variables, which are used to store data specific to that instance.

For example, consider a class called "Car" with instance variables for "make", "model", and "year". Each instance of the Car class would have its own values for these instance variables. One instance might have a make of "Honda", a model of "Civic", and a year of "2010", while another instance might have a make of "Toyota", a model of "Camry", and a year of "2015".

Instance variables are typically declared at the top of a class and are usually private, meaning they can only be accessed by methods within the same class. They are also usually initialized in the constructor of the class.

Here is an example of a class with instance variables in Java:

```
public class Car {
 private String make;
 private String model;
 private int year;
 
 public Car(String make, String model, int year) {
   this.make = make;
   this.model = model;
   this.year = year;
 }
 
 // getter and setter methods for instance variables
}
```

In this example, the instance variables "make", "model", and "year" are declared at the top of the class and are initialized in the constructor. The class also includes getter and setter methods for accessing and modifying the values of the instance variables.

To represent how long Shane has been running in seconds, we can use the expression t + 100.

This is because the terms given in the question state that Logan has been running for t seconds, and we need to find an expression for Shane.

It is mentioned that Shane has been running for more than 100 seconds, so we add 100 to t to represent Shane's running time.
