I tried to implement some coding stuff but I couldn't handle with the process. How can I do that? Here is the code snippet shown below.

    import java.util.Scanner;

    public class Main {
      public static void main(String[] args) {
        Scanner in = new Scanner(System.in); // detect inputs from the terminal input, System.in
        List<Student> students;
        while(in.hasNextLine()) { // while the scanner has a next line
          in.nextLine();
          String[] s = in.nextLine().split(",");
          students.add(new Student(s[0], s[1], s[2]));
        }
      }
      public class Student {
        public String name;
        public String surname;
        public int age;
        public Student(String name, String surname, int age) {
          // ...
        }
      }
    }

    import java.util.Scanner;

    public class Main {
      public static void main(String[] args) {
        Scanner in = new Scanner(System.in); // detect inputs from the terminal input, System.in
        List<Student> students;
        while(in.hasNextLine()) { // while the scanner has a next line
          in.nextLine();
          String[] s = in.nextLine().split(",");
          students.add(new Student(s[0], s[1], s[2]));
        }
      }
      public class Student {
        public String name;
        public String surname;
        public int age;
        public Student(String name, String surname, int age) {
          // ...
        }
      }
    }
