Programming Problem

GOD DAMMIT THIS SHIT IS PISSING ME OFF
Are there any Java and Eclipse knowledgeable programmers in here?
I keep getting this "Editor does not contain a main type" error. I tried searching for a main type (main class?) but no results pop up. Any help?

Oh and don't tell me ``go back to the imageboards'' isn't a meme for this board
Until the day that we use it without endorsing the message, I don't think it's right to relegate it to "meme"
