Cant seem to get memoryimagesource to work right

Question

Ok ive been messing with memory image source for a while here.
at least 6 hour's and i cant seem to get it to work in fullscreen.
i have tryed it a few different ways and im getting errors no matter what i do.
i figured id search the web for a example of memoryimagesorce in fullscreen but i can't find any!!!
anyways im haveing problems with drawimage().
i have the blue bar poping back up in this one even though i set undecorated to true.
when i try to use bufferstrategy it was even worse it locked up my comp 2 time's
here my horribly buggy code so far.
anyone have a example of the right way to use memory image source in fullscreen.

Now my code is painting exactly one time, the loop is going but nothing's happening. It should be displaying the different color lines moveing and changeing color.
Also ive come to a problem ive had before in the tutorial,
about not useing paint and update.
however thier should logically be a method like drawimage to use
or i should be able to use it. but its not doing anything.
the application window is drawn directly to the screen (active rendering).
This simplifies painting quite a bit, since you don't ever need to worry about paint events.
In fact, paint events delivered by the operating system may even be delivered
at inappropriate or unpredictable times when in full-screen exclusive mode.
Instead of relying on the paint method in full-screen exclusive mode, drawing code is usually
more appropriately done in a rendering loop:
public void myRenderingLoop() {
    while (!done) {
         Graphics myGraphics = getPaintGraphics();
         // Draw as appropriate using myGraphics
         myGraphics.dispose();
Such a rendering loop can done from any thread,
either its own helper thread or as part of the main application thread.
