well, only uninstall another jdk you have installed. don't uninstall your ide, or windows, or something.

just re downloaded and reinstalled jdk 1.5 update 6 after uninstalling the otehr sdk, and im still getting the error when i go to compile and run my code it says it cannot find a 100 classes, including animation.class, animationframe.class all in alphabetical order. Its like its not finding part of the library or something

hrm.
i've never used an ide, so i don't really know, maybe there is a way to "clean" your build or something?
at least try compiling via the command line:
javac MyClass.java
java MyClass
