Replacement for obsolete Hashtable class in Java

When I tried to use the hashtable class, Netbeans gave me an error saying:

While still supported, these classes were made obsolete by the JDK1.2 collection classes, and should probably not be used in new development.

However, I can't seem to find an example online on a better replacement for

Hashtable

. Any suggestions?

The most direct replacement of a Hashtable is a HashMap.

On difference that could be important is that all relevant methods of Hashtable are synchronized while they are not synchronized on HashMap.
