The above statement is true/false??

False.
Hashtable is thread safe (notice that only methods are synchronized).
HashMaps is not thread safe.

As of the Java 2 platform v1.2, this class (Hashtable) has been retrofitted to implement Map, so that it becomes a part of Java's collection framework. Unlike the new collection implementations, Hashtable is synchronized.
