    as always very clean n sufficient enough videos ....
    doubts
    1. why dont we use balanced tree in the first place instead of linkedList
    2. what is the criteria by which tree is made ...i mean go to left or right
    3.. how does hashMap.getKey() works

    • @ramasamyramasamy2423
      @ramasamyramasamy2423 2 роки тому

      Purpose of using balance tree later than linkedlist is about the size of the nodes added at specific index of the object created for the hashmap. Dismantling a sub tree of elements that added into balanced tree while deletion of elements in hashmap made, will be faster than removing an element from the linkedlist attached to the index of the object when deletion of elements size is larger. Dirtying the hashmap's elements will be slower when linkedlist size is increased...

  • @gowris442
    @gowris442 2 роки тому

    Bro here i have doubt in one place while doing get operation you are particular key hashing will happen and return index of the position of key. If its not match that key it will look oneby one node traverse if its not found it will return null value finally. Why we need to check one by one node to traverse and find out that key. If you do find exact key value means why could we can use balance tree logic to find out or some search mechanism to find out immediately not by way of traversing node one by one.

    @rishavgupta7868 2 роки тому

    Aren't we getting the index from the key within range of 0 to size-1 after applying hashcode() method, if so, what is hashing doing then, what's the difference between both,
    please anyone explain...

  • @harikrishnhaaraghuveeran5866

    Once the size of index increases from 16 , how will hashcode work for same key when it got inserted before and after index size increased?

    Hey Shabbir, Great explanation and i have doubt here, why we are using linkedlist in each bucket for storing the nodes,why cant we use simple arraylist?

    • @umeshkrishna8921
      @umeshkrishna8921 Рік тому

      Array list is the array representation so it doesn't have nodes to connect, where as linked list has nodes which are chained to maintain the links between the nodes.

  • @anupvishwakarma4214
    @anupvishwakarma4214 2 роки тому

    If the bucket size is more than 64 and one of the particular indexes reaches 8, then only the linked list will get converted to a Balanced tree. Please correct me if I am wrong.
