如何在使用构造函数初始化每个数组元素时从文件中读取并存储对象数组

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

public class Student {
    private String name;
    private int age;
    private String grade;

    public Student(String name, int age, String grade) {
        this.name = name;
        this.age = age;
        this.grade = grade;
    }

    public static void main(String[] args) {
        Student[] students = new Student[100]; // 创建存储学生对象的数组

        try (BufferedReader reader = new BufferedReader(new FileReader("data.txt"))) {
            String line;
            int index = 0;

            while ((line = reader.readLine()) != null && index < students.length) {
                String[] data = line.split(","); // 假设数据以逗号分隔

                if (data.length == 3) {
                    String name = data[0];
                    int age = Integer.parseInt(data[1]);
                    String grade = data[2];

                    students[index] = new Student(name, age, grade);
                    index++;
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 打印存储的学生对象
        for (Student student : students) {
            if (student != null) {
                System.out.println("Name: " + student.name);
                System.out.println("Age: " + student.age);
                System.out.println("Grade: " + student.grade);
                System.out.println("--------------------");
            }
        }
    }
}
