i have java installed but how can i run feed the beast since it isnt in the java format for the launcher
I can just assume you are referring to the custom map for minecraft called feed the beast?
Feed the beast is a modpack launcher, similar to technicpack launcher. There's a .jar download on feed-the-beast.com. are you not able to execute that?
If you have windows and downloaded the .jar that won't work, You'll have toget the .exe version.
get the .jar right click and do open with... and select java
