Learn Java from Scratch - A Beginner's Guide - Step 00 - Introduction to Array and ArrayList - Section Introduction with

This video introduces the concepts of arrays and Arraylist through a challenge involving student marks. It covers creating a student with a list of marks, performing operations like sum, max, min, and average, and adding or removing marks. The video explains the need for arrays, operations allowed on them, and how Arraylist simplifies these tasks. The next video will discuss the need for an array.
