TreeMap - Search Time Complexity

Question

What is the time complexity of a get() and put() in a TreeMap?

Is the implementation same as a Red-Black Tree?

Answer 1

From here: http://java.sun.com/javase/6/docs/api/java/util/TreeMap.html

This implementation provides guaranteed log(n) time cost for the containsKey, get, put and remove operations

Answer 2

TreeMap is:

A Red-Black tree based NavigableMap implementation.

This implementation provides guaranteed log(n) time cost for the containsKey, get, put and remove operations. Algorithms are adaptations of those in Cormen, Leiserson, and Rivest's Introduction to Algorithms.
