//------------Task 2. Create a list of students by reading from student_hobbies.txt and display the list. //You will also need to create a Student class, which has at least //two data fields: student name and an ArrayList of hobbies (String-type). System.out.println("\n------------ Task 2. Create a list of students by reading from student_hobbies.txt."); ArrayList <Student> studentList = new ArrayList<Student>(); studentList = readFile("student_hobbies_JU.txt"); for (Student s: studentList) { System.out.println(s); }

It looks like you have a good start to Task 2. However, in order for this code to work, you'll need to implement the `Student` class and the `readFile()` method.

Here's an example implementation of the `Student` class:

import java.util.ArrayList;

public class Student {
    private String name;
    private ArrayList<String> hobbies;

    public Student(String name, ArrayList<String> hobbies) {
        this.name = name;
        this.hobbies = hobbies;
    }

    public String getName() {
        return name;
    }

    public ArrayList<String> getHobbies() {
        return hobbies;
    }

    @Override
    public String toString() {
        return name + ": " + hobbies.toString();
    }
}

This class has two data fields (`name` and `hobbies`) and a constructor that takes in a name and a list of hobbies. It also has getter methods for each data field and an overridden `toString()` method that returns a string representation of the `Student` object.

Here's an example implementation of the `readFile()` method:

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        System.out.println("\n------------ Task 2. Create a list of students by reading from student_hobbies.txt.");
        ArrayList<Student> studentList = readFile("student_hobbies_JU.txt");
        for (Student s : studentList) {
            System.out.println(s);
        }
    }

    public static ArrayList<Student> readFile(String filename) {
        ArrayList<Student> studentList = new ArrayList<>();
        try (BufferedReader br = new BufferedReader(new FileReader(filename))) {
            String line;
            while ((line = br.readLine()) != null) {
                String[] parts = line.split(":");
                String name = parts[0];
                String[] hobbies = parts[1].split(",");
                ArrayList<String> hobbyList = new ArrayList<>();
                for (String h : hobbies) {
                    hobbyList.add(h.trim());
                }
                Student s = new Student(name, hobbyList);
                studentList.add(s);
            }
        } catch (IOException e) {
            System.err.println("Error reading file: " + e.getMessage());
        }
        return studentList;
    }
}

This code reads from the `student_hobbies_JU.txt` file (assuming it's in the same directory as the program) and creates a list of `Student` objects. It then displays each `Student` object using the `toString()` method we defined earlier.

I hope this helps! Let me know if you have any questions.
