Learn Java from Scratch - A Beginner's Guide - Step 14 - First Look at ArrayList - Refactoring Student Class to Use Arra

The video tutorial focuses on refactoring a Student class by changing its internal structure from an array to an ArrayList. It explains the process of converting arrays to ArrayLists, utilizing Java's Collections utility methods for operations like finding maximum and minimum values, and implementing a toString method for better output representation. The tutorial emphasizes maintaining functionality while altering internal code structure, ensuring that external behavior remains unchanged. Future steps include adding methods for deleting and adding marks.

Describe the process of adding elements to an array list as outlined in the video.
