Trying to run space invaders

[Guild_Wars_owns]

Thought i would move my question to here as im a newbie;

I got this space invaders game and have compiled it, the main source is Game.java , but i cant run it , how would i do this ?

if somebody could make it run themselves then tell me how to it would be really great

Could it be not running properly because it says it uses unsafe or unchecked things when i compiled it?

Dont worry ive fixed it now , i did same thing as before and it magically worked
( java org.newdawn.spaceinvaders.Game)

making my version now from scratch- garden invaders

Thanks for all the help you guys rule
