Update: From Java 8, when different keys hash to the same bucket and when the bucket capacity reaches its TREEIFY_THRESHOLD(8), the nodes in bucket will be stored in a balanced binary tree structure thereby reducing the worst case time complexity to O(log n) from O(n). When nodes in the bucket starts getting reduced and when the number of nodes in bucket reaches UNTREEIFY_THRESHOLD(6), the nodes in a bucket will again be stored in a Linked List structure.
