Java Interview Shorts - 6 When to Choose an ArrayList Over LinkedList in Java ?

In this video we will understand the uses of an ArrayList in java. Arraylist in java backed by an array. Array is being index based gives us the benefit of the search performance. In array list the search time is constant. Which is o(1) but when it comes to modification like insertion and deletion operation, array list is a worse selection because of the shifts of elements.

ArrayList - for frequent search operations
LinkedList - for frequent insertions and deletions

For visual learners this explanations with videos demo are the best thing to memorize this. Thnx

If we want to insert an elements inbetween in linked list is O(n) for search and O(1) for insertions so its also O(n) only inserting element at beginning or deleting an elements in beginning is O(1) compare to ArrayList

@Abilash a question, Correct if i am wrong

I think Arraylist will maintain an insertion order while adding a new element to it. But you said while we add an element to Arraylist it will get stored in random places

Could someone or Abilash answer me or correct me !

[jayakumarsivasankar]

Great..
Could you please help us with time complexity with different collections

[movietrailer]

Use ArrayList if searching element in List is main taks
Use LinkedList if modifying element is main task.
