Is a Java hashmap really O(1)?

http://stackoverflow.com/questions/1055243/is-a-java-hashmap-really-o1

Unless these hashmaps are vastly different from any of the hashing algorithms I was bought up on there must always exist a dataset.. to though there are some algorithms quicksort and many hashing algorithms for example that are much more likely to approach.. difficult nut to crack. The efficiency of a particular hashing algorithm depends on the data that's being fed to it but there..
