WebDepending on your choice of data structure, the performance (worst and average case) of insert, delete and search changes. According to Coding-Geek.com, Java 7's HashMap implementation uses a linked list (unsorted), but Java 8 uses a balanced binary tree instead. Of course, insert/delete/search in a balanced tree of size n has complexity O(log n).
