Maintaining the Order of Inserting and Retrieving Java Objects Using Hashtable

Maintaining the Order of Inserting and Retrieving Java Objects Using Hashtable

We know that using Hashtable we can put and get the java objects relatively fast. But Hashtable does not maintain the order in which you add and retrieve the objects. Using a combination of hashtables we can accomplish this. With the following tip you can maintain the order.

  java.util.Hashtable hash = new java.util.Hashtable();for(int i = 0; i 

When you retrieve it, and if you want to retrieve the second item, which might be value associated with "name1" then you can have code:

 for(int i=0; i 

Also when we loop through the objects we can retrieve all the objects in the order in which they were inserted.
