How to create a sequence of flashes ...

Question

hey i'm trying to create a simple version of a simon says game. where the applet will have (some image) and it will flash (some image) in differnent sequences. i want it to randomly choose a sequence - that's the first part... then I would like to have the sequence extended on the next time around... I can't really explain it but here is some code that I have but I can't really understand it
  //     Setup the sequence array
  public void sequence() {
    int prev1= 0, prev2= 0, curr;
    for (int a= 0; a<imgSquare; a++) {
      while (prev1 == (curr= rand(7) + 1) || prev2 == curr) ;
      prev2= prev1; prev1= seq[a]= curr;
    seqLength= min_seqLength;
   //     Random numbers
  int rand(int siz) {
    return Math.abs(rand.nextInt()) % siz;
  } i think this is what is supposed to happen, but i'm very new to java so I am not really sure what to do first.
I would like to have seven squares on the applet and each applet flashes in different sequences, the first one short, the next one longer...and so on.
can anybody please help me out with this???
how should I structure this program and where should I start first?
Thank you in advance

Answer 1

The basic idea here is,
--> Store the images in an array of size 7
loop {
--> Randomly generate an integer in the range 0 to 6
--> Get the image out of the array with this random index
--> Update the image on your applet square(or whatever)
} // end loop
