javac inoperable

HELP! I am a moron when it comes to this stuff but I am trying very hard to learn. I followed the instructions, I believe, exactly, I have recenlty downloaded Java onto 2 different computers (also 2 different versions, I believe). I am trying to learn how to program but I cannot get anything to compile. I went through adding the PATH. Nothing is working.

Please help me!
