Building MIDlets - Beginning J2ME: From Novice to Professional - page 13

When you enter a word into Jargoneer , it connects to a server to find the definition. Running
this MIDlet will allow you to appear cool in the company of your hacker friends. When someone
uses an unfamiliar word, like “cruft” or “grok,” you can surreptitiously key the word into your
mobile phone and see a definition in a few seconds.
Jargoneer 's source code is provided in Listing 2-1. If you don't want to type it in, you
can download all of the code examples in this topic from the Downloads page at
