List Array Notation in Apex | Salesforce Development Course

[@SathishSfdc-oz5xs]

I noticed few things:
1. by default all the array notations for list are null and when you have list of size 4 which is Index {0,1,2,3) - value {null,null,null,null} and if you add the value for ex. L4[3] = 8; then it becomes {null,null,8,null}.
2. Now if i have this list {null, 3 , 8, null} , then i remove L4.remove(3); then it becomes {null,3,null} , which means the position itself gets removed and replaced by next value.
3. after performing L4.clear(); I was not able to add any value to this List, is there any way to over ride that?

L4[0] = 1; syntax to replace a value at 0th index.
Or, also, you check the list methods in documentations.
