This is my specific instruction. so I want you to make a new class called StudentsService in the com.sait.itsc315.services package AND modify AppDriver. I will attach my appdriver, student, students class below. Thank you!

AppDriver.java

package com.sait.itsc315.application;
import java.io.*;
import com.sait.itsc315.problemdomain.*;

public class AppDriver {
/**
 * Entry point for program.
 * @param args
 * @throws IOException
 */
public static void main(String[] args) throws IOException {
 Students students = new Students();
 
 // Create instance of StudentsService
 
 // Print "Honor Students: "
 // Loop through honor students
  // Print each students information
 
 // Print "Declining Students: "
 // Loop through honor students
  // Print each students information
}
}
 

 

Student.java


package com.sait.itsc315.problemdomain;


public class Student {
private int id;
private String name;
private double gpa;

/**
 * Constructor for a student.
 * @param id Student's ID

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

/**

public void setId(int id) {
this.id = id;
}

/**

public String getName() {
return name;

/**

public void setName(String name) {
this.name = name;

public String toString() {
return String.format("%d - %s - %.2f", this.id, this.name, this.gpa);

Students.java


package com.sait.itsc315.problemdomain;

import java.io.*;
import java.util.*;


public class Students {
public static final String TEXT_FILE = "res/students.csv";

private ArrayList students;

public Students() throws IOException {
this.students = new ArrayList<>();

this.loadFromTextFile();
}

/**
 * Loads students from text file.
 * @throws IOException
 */
private void loadFromTextFile() throws IOException {
BufferedReader br = new BufferedReader(new FileReader(TEXT_FILE));

String line = br.readLine();

while (line != null) {
String[] parts = line.split(",");

int id = Integer.parseInt(parts[0]);
String name = parts[1];
double gpa = Double.parseDouble(parts[2]);

Student student = new Student(id, name, gpa);
this.students.add(student);

line = br.readLine();
}
}

/**
 * Gets the students.
 * @return List of students.
 */
public ArrayList getStudents() {
return this.students;
}
}

Instructions 1. Create a new class called Students Service and place it in the com.sait.itsc315.services package. The class will have a: Constructor that takes in a Students object and stores it in a field. Method called getHonorStudents that filters the students with a GPA greater than or equal to 3.8 and returns an ArrayList containing the found student objects. Method called getDecliningStudents that filters the students with a GPA less than or equal to 2.0 and returns an ArrayList containing the found Student objects. 2. Modify the AppDriver so it creates a Students Service object and displays both the honor and declining students (as separate lists). Notes You CANNOT modify the Student or Students classes to complete this lab exercise.
