Java & TUIO Project - Coding trouble

This is what I have so far;
import TUIO. *,
TuioProcessingtuioClient;
HashMapSymbols=newHashMap();
//other declarations
void setup()
{
}
void draw()
{
}
voidaddTuioObject(TuioObjecttobj)
{
}
voidremoveTuioObject(TuioObjecttobj)
{
}
voidupdateTuioObject(TuioObjecttobj)
{
}
voidaddTuioCursor(TuioCursortcur)
{
}
voidupdateCursor(TuioCursortcur)
{
}
voidremoveCursor(TuioCursortcur)
{
}
voidrefresh(TuioTimebundleTime)
{
redraw();
}


Under void setup i know i must add my symbols to track my fiducials but after that I am stuck and don't know what to do. My game is a tic tac toe game. where the x or the 0 will appear after a math question has been solved. and after the question is solved and the answer is correct is will move on to another screen where moving balls will appear and must be burst by placing a fiducial over it, after all the balls have been burst it will go back to the game and resume.

I know that this is the absolute beginning and basic of programming but I barely have any programming background and just need a little bit of code or something to help me move along, give me a little push.

Yup, I'm doing just that, thank you!
