This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
In java, a Hashtable stores key/value pairs in a hash table, where you specify an object as a key & a value linked to it is obtained. Key is hashed & the resulting hash code is used as the index at which the value is stored within the table. Wishing happy programming in Java.
