Java Question

java and need to help me learn.

Instructions ITN 261: Gradebook – javaFX Problem statement: You are tasked with writing a program that will keep track of student grades and display them in a graphical program. Requirements: Student information should be stored within a Student class object We must keep track of each students: Name – String GPA – double Id – int Standing – int 0 corresponds to freshman 1 corresponds to sophomore 2 corresponds to junior 3 corresponds to senior Grading details: Correct usage of OOP concepts (80%) Correct class design and usage of class instances (30%) Correct usage of javaFX objects and classes (30%) Other supporting code/logic (20%) Program runs/correct results (10%) Formatting/Indentation (10%) Starter Code: import java.util.ArrayList; import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.layout.VBox; import javafx.scene.text.Text; import javafx.stage.Stage; public class Gradebook extends Application { static ArrayList roster = new ArrayList<>(); public static void main(String[] args) { launch(args); } @Override public void start(Stage primaryStage) throws Exception { // TODO: Make the necessary changes to display the class // roster using a JavaFX window rather then the console. roster.add(new Student(“John”, 3.5, 700000001, 0)); roster.add(new Student(“Jane”, 3.2, 700000011, 0)); roster.add(new Student(“Mike”, 3.9, 700000012, 1)); roster.add(new Student(“Mary”, 4.0, 700000013, 2)); roster.add(new Student(“Joseph”, 3.1, 700000002, 3)); for (Student each: roster) { System.out.println(each); } } } Sample output: Gradebook name = John, gpa = 3.5, id = 700000001, class = Freshman name = Jane, gpa = 3.2, id = 700000011, class = Freshman name = Mike, gpa = 3.9, id = 700000012, class = Sophomore name = Mary, gpa = 4.0, id = 700000013, class = Junior name = Joseph, gpa = 3.1, id = 70000002, class = Senior

To create a JavaFX program for your gradebook application, you need to make the necessary changes to the provided code. You will need to create a graphical user interface to display the class roster. I’ll guide you through the process step by step:
First, you need to create a Student class that stores student information. It appears you already have a Student class; ensure that it has the necessary fields and constructor. Here’s a simplified version of the Student class for reference:
javaCopy code
public class Student {
private String name;
private double gpa;
private int id;
private int standing;

public Student(String name, double gpa, int id, int standing) {
this.name = name;
this.gpa = gpa;
this.id = id;
this.standing = standing;
}

// Implement getters and setters for the fields if necessary
// …
}

Next, you need to update the start method of your Gradebook class to create a JavaFX window and display the class roster. You can use JavaFX components such as VBox and Text to accomplish this. Here’s a modified start method:
javaCopy code
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle(“Gradebook”); // Set the window title

VBox vbox = new VBox(); // Create a vertical box to hold the student information

for (Student student : roster) {
Text studentText = new Text(“name = ” + student.getName() +
“, gpa = ” + student.getGpa() +
“, id = ” + student.getId() +
“, class = ” + getStandingName(student.getStanding()));
vbox.getChildren().add(studentText); // Add each student’s information to the VBox
}

Scene scene = new Scene(vbox, 400, 300); // Create a scene with the VBox
primaryStage.setScene(scene);

primaryStage.show(); // Display the window
}

// Helper method to get standing name from the integer standing
private String getStandingName(int standing) {
switch (standing) {
case 0:
return “Freshman”;
case 1:
return “Sophomore”;
case 2:
return “Junior”;
case 3:
return “Senior”;
default:
return “Unknown”;
}
}
Save to grepper
Ensure you have the required JavaFX libraries and dependencies in your project setup.
Make sure to import the necessary JavaFX classes at the beginning of your Java file:
javaCopy code
import javafx.application.Application;
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.layout.VBox;
import javafx.scene.text.Text;
Save to grepper
The provided sample output is no longer needed, as you will be displaying the student information in the JavaFX window.
To run the program, call launch(args) in the main method as you did before.
Your JavaFX application is now ready to display the class roster. When you run the program, it will open a window with the student information displayed vertically in a VBox. The student information will be formatted similar to the sample output, but it will be presented in a graphical user interface.
