title: Non-static method cannot be referenced from a static context (Java)
body: <p>I'm newer to programming and keep getting the non-static method cannot be referenced from a static context when calling my floor class from my ant class.  I've removed all statics and am still getting this error, if someone could point me in the right direction or let me know what the issue is that would be great, thanks.</p>
