Is java.util.Hashtable thread safe?

Question

It\'s been a while since I\'ve used hashtable for anything significant, but I seem to recall the get() and put() methods being synchronized.

The JavaDocs don\'t ref

Answer 1

Yes, Hashtable thread safe, so only one thread can access a hashtable at any time

HashMap, on the other side, is not thread safe (and thus 'faster').
