Java Programming Session 28: ArrayList Internal Structure
Hello Everyone,
Welcome to my channel PriyankaazITSchool.
In this live session I have explained about Collection Framework,ArrayList internal structre .
Notes....
ArrayList
----------------
ArrayList is class implements List interface
The underline data structure is growable Array
Duplicates elements allowed
Insertion order is maintain
Null insertion is possible
ArrayList and Vector class implements RandomAccess interface so that we can access only random elements with the same speed
Hence, if our frequent operation is retrieval operation then
ArrayList is the best choice.
I hope you will love it.
Keep Learning!
Thanks,
Priyanka Nigade
