In Java, the TreeMap class is implemented based on a red-black tree, a balanced binary search tree.
The complexity of the insert operation (put) in TreeMap is O(log n), where n is the number of elements in the map.
This is because, to insert:
- Find the position for the new key (search in the tree) — O(log n).
- Insert the element and, if necessary, balance the tree (rotations and recoloring) — also O(log n) in the worst case.
Therefore, insertion into TreeMap is efficient and scalable due to its balanced data structure.
