[SOLVED] Best java jdk update?

I am following some vids on java game development, and i came to where i had to start sprites, so i set up:

private Sprite sprite; to create the sprite variable but it doesn't let me create it, then i upgraded to the 6_0_24 java jdk update and it wouldn't let me do animations anymore. Is there a good set jdk for java game development??

I really want to continue.
