Help: I deleted java..

So a couple of days ago I kept on noticing that when I restarted my computer terminal and a little java app (although clicking on it did nothing) would appear in my dock. I then had the "bright" idea of deleting it by just looking for the application or whatever was named Java in my finder. I believe I successfully deleted it then went to the Java website and downloaded the newest version. I restarted and now it seems that one of my applications which runs on java now does not open, it worked perfectly before. I have since deleted java and am at a loss for what to do.

I am running 10.9.4 OSX Mavericks.

Any help would be greatly appreciated.

 

Thank you simsaladimbamba, I looked for a download of Java on the apple website and it worked wonderfully.
