Question

i use Selenium to get some Lecture information what i listen now
and i stored it to List<String> list as String
There is a list of lectures that I am currently listening to,
but each lecture has different information that contains the form of the lecture.

after store that into List<String> list
and when i use this

How can i store two forms of lecture in different List?
The goal is to put it into the database
but before that i want to seperate into different List

Answer 1

You should create an object Lecture, for example:

class Lecture {
  private int number;
  private String categorization;
  // omitted
}

Then parse field by field.
