title: java : non-static variable cannot be referenced from a static context Error
body: <p>The following code is generating an error on the variable <code>con2</code> saying  <code>"non-static variable con2 cannot be referenced from a static context Error."</code> I Googled for a resolution and they are suggesting the variable isn't initalized yet to make the methods available. Am I initializing this incorrectly? I also tried changing things to public but that didn't help either.</p>
