Pulling my hair out over this...

Question

Background Info: I'm a college student, taking an introduction to programming class that is using Java. We are only to chapter 6, so I'm still very new at this. Dr Java is the compiler of choice in this text.
I have been given an assignment to create a method that counts all the white pixels in a given image. I have the thought pattern down, but I am running into a problem with my looping.
        public void whtCount()
      Pixel pixel = null;
      int totalRGB = 0;
      int whitePixels = 0;
     for (int x = 0; x <= this.getWidth(); x++)
     {for (int y = 0; y <= this.getHeight(); y++)
       {if (x < this.getWidth() && y < this.getHeight()) {pixel = this.getPixel(x,y);
      totalRGB = (pixel.getRed() + pixel.getGreen() + pixel.getBlue());
      if (totalRGB == 765)
      {whitePixels = whitePixels + 1;}
     else {System.out.println("poop " + whitePixels);}
        }I just came upon an interesting change, and this is the result. The good news is that it outputs the correct number of white pixels (I created a 10x10 all white JPEG). The flip side is that it is still outputting lots of times. It outputs at the end of each row; the most curious thing is that it outputs the result multiple times. When I ran this method on the previously mentioned JPEG this is what was returned:
poop 10
poop 20
poop 30
poop 40
poop 50
poop 60
poop 70
poop 80
poop 90
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100
poop 100*Coded because it won't display properly otherwise.
At least this is some forward progression. I still can't figure out why it is printing more than once, much less such a specific number of times. Dr Java will display as many results as is given, so I know it isn't just cutting it off. I learned this earlier when I got "poop 10" about a bazillion times.
EDIT: I thought I should probably mention that I am using the classes that came with the book. This particular method is to go in the pictures class. I can scrounge up an unedited one if it would help.

Answer 1

The reason I included the if statement was to keep the statement from running every single time the statements were executed. I see now that I did that needlessly.
Thank you so very much. Once you said that, it just sort of clicked in my mind (followed shortly by a feeling of stupidity, but everyone's new at some point, I guess).
Thanks again. I got it all working.
