For this discussion assignment, please provide your response to each of the below questions in a minimum of 200 words and a maximum of 250 words.
In the context of Java programming, discuss the significance of having a thorough understanding of variables and data types. Compare and contrast the various data types offered in Java, including both primitive data types and reference data types. Additionally, explain the distinct roles played by variables and data types in the storage and manipulation of data. Illustrate your points with relevant examples to reinforce your explanations.
Elaborate on the concept of operator precedence in Java and how it affects the evaluation of expressions. Discuss how understanding operator precedence can help in avoiding potential errors while writing code and improving program efficiency. Demonstrate your understanding by providing examples that highlight the importance of considering operator precedence in Java programming.
In the context of Java programming, engage in a comprehensive discussion regarding the significance and diverse applications of conditionals. Analyze and compare the distinct types of conditional statements available, including if-else, switch-case, and ternary operators, focusing on their syntax, functionality, and use cases. Examine the advantages and limitations of each conditional statement type, while differentiating the scenarios in which they are most effective. Elaborate on the factors that influence the selection of one conditional statement over another.
Please include a word count. Following the APA standard, use references and in-text citations for the textbook and any other sources.

can i have netbean app coodiding an user interface Problem Statement:
You are tasked with developing a Library Book Reservation System to manage book reservations
for a public library. The system should allow users to reserve books, process reservations, and
remove reservations as necessary.
Scenario:
The public library wants to streamline its book reservation process. Users can reserve books online
through the library’s website. Once reserved, the library staff processes the reservations and
notifies users when their books are ready for pickup.
Application Details:
Each book reservation contains the following attributes:
Attributes Details
reservation_id Unique identifier for each reservation
book_title Title of the reserved book
author Author of the reserved book
user_name Name of the user who reserved the book
contact Contact information of the user
status Current status of the reservation (e.g., Pending, Processing, Completed)
Requirements:
1. Create a class named ‘BookReservation’ to represent each book reservation. Include attributes
for the reservation details mentioned above.
2. Implement a queue data structure using arrays to manage the book reservations.
3. Provide the following menu options for user interaction:
Menu Details
Reserve Book Allow users to reserve a book by providing the necessary details.
Enqueue the reservation into the queue
Process Reservation Change the status of a reservation. If the status changes to
“Completed,” notify the user that their book is ready for pickup by
displaying a message.
Remove Reservation Remove a reservation from the queue. If the reservation is being
processed, ask the user to confirm the cancellation
View Reservations Display all reservations in the queue and a tabular format.
Exit Terminate the program
4. Handle all the exceptions.
5. Implement a graphical user interface.

Submission Guidelines:
• Implement the Library Book Reservation System in Java, focusing on arrays, classes, and
queue data structure concepts

Given main(), complete the SongNode class to include the printSongInfo() method. Then write the Playlist class’ printPlaylist() method to print all songs in the playlist. DO NOT print the dummy head node.
Ex: If the input is:
Stomp!
380
The Brothers Johnson
The Dude
337
Quincy Jones
You Don’t Own Me
151
Lesley Gore
-1
the output is:
LIST OF SONGS
————-
Title: Stomp!
Length: 380
Artist: The Brothers Johnson
Title: The Dude
Length: 337
Artist: Quincy Jones
Title: You Don’t Own Me
Length: 151
Artist: Lesley Gore
import java.util.Scanner;
public class Playlist {
// TODO: Write method to ouptut list of songs
public static void main (String[] args) {
Scanner scnr = new Scanner(System.in);
SongNode headNode; SongNode currNode;
SongNode lastNode;
String songTitle;
int songLength;
String songArtist;
// Front of nodes list headNode = new SongNode();
lastNode = headNode;
// Read user input until -1 entered
songTitle = scnr.nextLine();
while (!songTitle.equals(“-1”)) {
songLength = scnr.nextInt();
scnr.nextLine();
songArtist = scnr.nextLine();
currNode = new SongNode(songTitle, songLength, songArtist);
lastNode.insertAfter(currNode);
lastNode = currNode;
songTitle = scnr.nextLine();
}
// Print linked list
System.out.println(“LIST OF SONGS”);
System.out.println(“————-“);
printPlaylist(headNode);
}
}

*Key principles of Object-Oriented Programming (OOP) supported by Java:*
Java supports the key principles of OOP, including:
– *Encapsulation:* Bundling data and methods that operate on the data into a single unit (class).
– *Inheritance:* Allowing a class (subclass) to inherit properties and behavior from another class (superclass).
– *Polymorphism:* Providing the ability for objects to be treated as instances of their superclass, allowing for methods to be overridden and objects to be referenced by their superclass type.
– *Abstraction:* Hiding complex implementation details and providing a simplified interface for interacting with objects.
– *Association:* Defining relationships between classes, such as one-to-one, one-to-many, and many-to-many associations.
– *Composition:* Building complex objects by combining simpler objects.
– *Aggregation:* Representing “has-a” relationships between objects, where one object contains another object as a part.
– *Interfaces:* Defining contracts for classes to implement, allowing for multiple inheritance-like behavior.
– *Encapsulation:* Protecting internal data from direct access and manipulation by providing public methods to interact with the data.
Java achieves these principles through its class-based object-oriented model, supporting features like classes, interfaces, inheritance, and polymorphism.

Overview:
This project is to implement two sorting algorithms. The first sorting algorithm is an 𝑂(𝑁2)
algorithm: either Selection Sort or Insertion Sort or Bubble Sort. The second algorithm is Quicksort.
Your Quicksort algorithm must use at least two practical improvements that were discussed in
class. With all of this done, you will be asked to gather some data about the running time and plot it.
Requirements:
You must implement the two sorting algorithms above. They should sort the numbers in ascending
order (smallest to largest). When you submit your project, you must have functioning code for both
sorting algorithms, but you can comment out the lines in your main method which actually do the
sorting (so I can uncomment a single line to switch the sorting algorithm). If you’d like, you can ask
the user which sorting algorithm and do it that way.
Youmustalsohaveamethod/functionconfirmSorted(). Thisfunctionshouldtakeyourarrayof
numbers, verify that it is sorted in ascending order, and return a Boolean. If the numbers are
confirmed to be sorted, print out “Confirmed sorted” and if they aren’t sorted, print out “Confirmed
NOT sorted”. Do this before and after the sort.
Data analysis:
In addition to your code, you’ll be asked to try out each sorting algorithm will datasets of different
sizes and record the running time (in milliseconds). With this data, you should create a table and
graph like the one below. In a paragraph or two, please write what you’ve discovered with this data,
explain what is happening with the data and why. You will be provided with datasets of the following sizes: 10, 100, 1000, 5000, 10000, 25000, 50000,
75000, 100000, 250000, 500000, 750000, 1000000, and 10000000. Please include results for all
these datasets in your analysis. Some combinations of algorithm and dataset size won’t be feasible
and may be excluded (the slower algorithm will start to take a VERY long time with large datasets).
