HashTable is Synchronized, at a time only one thread or process can take up the HashTable object instace and do the modifications and other process.

I'm not agree with someone said that Hashtable is not synchronized. That's wrong!!Plz, look at website http://java.sun.com/j2se/1.5.0/docs/api/index.html for more information.

This example creates a hashtable of numbers. It uses the names of the numbers as keys:
     Hashtable numbers = new Hashtable();     numbers.put("one", new Integer(1));     numbers.put("two", new Integer(2));     numbers.put("three", new Integer(3)); 
To retrieve a number, use the following code:
     Integer n = (Integer)numbers.get("two");     if (n != null) {         System.out.println("two = " + n);     } 
As of the Java 2 platform v1.2, this class 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.
