hi, I downloaded all files ad tested the test... but now I really don't know what to do

.
I mean, i never wrote a game in java, i found just one elementary tutorial (the space invaders one)
and it doesn't answer me a lot of questions...
1. when i want to try my game, what shuold I do to play it? because I don't understand all the commands in java -cp .;res;jar\lwjgl.jar;jar\lwjgl_test.jar;jar\lwjgl_util.jar;jar\lwjgl_fmod3.jar;jar\lwjgl_devil.jar;jar\jinput.jar;
-Djava.library.path=native\win32 org.lwjgl.test.WindowCreationTest
so I don't know what to write in the prompt...
2. in the space invaders tutorial it summons lot of things i don't know:setIgnoreRepaint,getBufferStrategy(),etc.
so, I guess I have a LOT to learn before i can use LWJGL, but what I am asking is: what do I have to learn and where can I learn it?
