When to use the Array list and when the Linked list?
ArrayList - >
When frequent operation is retrieving the elements from the middle.(Random access)
LinkedList -> when frequent operation is insert / delete at the middle.

Array after n elements :
"SORRY buddy, I'm full."
ArrayList after the n+1 element arrives :
"Come here bro, I'll make a space for you.... Come here"

ArrayList is dynamicโฆ but not free โ ๏ธ
When it grows, Java creates a bigger array, copies data, and drops the old one ๐
Resizing costs memory & performance.

๐ง Today I learned about ArrayList in Java โ a dynamic way to store and manage data.
Unlike arrays, it can grow or shrink as needed โ no fixed size, just flexibility ๐ช
Adding, removing, iterating โ itโs all easier now.
One step closer to mastering Java โ๐ฅ
