Newbie here: Running my processing app on a blackberry

So I began designing an app (it's a 2d fighting game) and I've been coding it in processing. I don't have the slightest clue on how to make an app for blackberry or ipod or anything like that, I'm just out of my first year of programming. My app runs fine atm on my pc when I run it from within processing (like I open the code and hit the arrow button). I haven't completed the app yet but I know that I want my next move to be running it on a blackberry.

So can anyone give a total noobtardo (me) some advice on how to do this? Considering I have almost no knowledge of computer science besides some programming basics..

thank you in advance!

How do I give my transparent images color?

Atm I have these two images

blackBackground.JPG:

and rightStanceBoxer.png:

and this is the code:

PImage rightStanceBoxer = loadImage("blackBackground.JPG").get(0,0,201,200);

rightStanceBoxer.mask(loadImage("rightStanceBoxer.png"));

this gives me a black stickman image with a transparent background so you can see the background behind him. here's a screenshot:

then I use image() and specify where on the screen I want the image to go..

I want to add color to this image but I have no idea how. I tried to use the tint() function right before image() is called but that did not do anything. I tried looking at the api and other online sources but I am still confused.. can anyone give me some tips?

ArrayOutOfBoundsException: Coordinate out of bounds!

I'm creating my first game and it's been going well so far, but then I ran into this error.
Ok so my window is 1024x768. I am getting this exception: "ArrayOutOfBoundsException: Coordinate out of bounds!"

here the method where the exception happens:

public void drawHealthBars(){

  PImage purpleHealthBar = loadImage("purpleHealthBar.jpg"); //this size of this image is 1x50 pixels

  PImage greenHealthBar = loadImage("greenHealthbar.jpg");   //this size of this image is 1x50 pixels

  int cHealth1 = model.player[0].getCurrentHealth(); //this value is 100

  int tHealth1 = model.player[0].getTotalHealth(); //this value is 100

  int cHealth2 = model.player[1].getCurrentHealth(); //this value is 100

  int tHealth2 = model.player[1].getTotalHealth();   //this value is 100

  int numBars1, numBars2;

  if(cHealth1 > tHealth1/2) numBars1 = 2;

  else if (cHealth1 > 0) numBars1 = 1;

  else numBars1 = 0;

  if(cHealth2 > tHealth2/2) numBars2 = 2;

  else if (cHealth2 > 0) numBars2 = 1;

  else numBars2 = 0;

  if(numBars1 == 2){

   float barSize = (float)(cHealth1-tHealth1/2) / (float)(tHealth1/2)*450;

   greenHealthBar.resize((int)barSize, 50);

   purpleHealthBar.resize(450, 50);

   image(purpleHealthBar, 25, 25);

   image(greenHealthBar, 25, 25);

  }

  else if(numBars1 == 1){

   float barSize = (float)(cHealth1) / (float)(tHealth1/2)*450;

   fill(100);

   rectMode(CORNER);

   rect(25, 25, 450, 50);

   purpleHealthBar.resize((int)barSize, 50);

   image(purpleHealthBar, 25, 25);

  }

  if(numBars2 == 2){

   float barSize = (float)(cHealth2-tHealth2/2) / (float)(tHealth2/2)*450;

   greenHealthBar.resize((int)barSize, 50);

   purpleHealthBar.resize(450, 50);

   image(purpleHealthBar, width -475, 25);

   println( width - (25+barSize));

   image(greenHealthBar, width - (25 + barSize), 25); //THIS IS WHERE THE EXCEPTION OCCURS!

  }

  else if(numBars2 == 1){

   float barSize = (float)(cHealth2) / (float)(tHealth2/2)*450;

   fill(100);

   rectMode(CORNER);

   rect(width-475, 25, 450, 50);

   purpleHealthBar.resize((int)barSize, 50);

   image(purpleHealthBar, width - (25+barSize), 25);

  }

  textFont(font0);

  fill(0);

  textAlign(CENTER);

  text(cHealth1+"/"+tHealth1, 250, 65);

  text(cHealth2+"/"+tHealth2, width-250, 65);

}

this method gets called in the main draw() loop.

The code works fine and displays the health bars until this method gets called when the mouse is pressed:

model.decreaseHealth(10, 0);

here is the decreaseHealth method:

public void decreaseHealth(int n, int play){



   player[play].currentHealth-=n;

   if (player[play].currentHealth < 0)

   player[play].currentHealth = 0;

  }

I do not get an exception if I called this method at the same time as the other decrease health method:

model.decreaseHealth(10,1); //note the only difference is the second parameter is a 1 instead of 0

I don't know why calling the method on player[1] makes the exception not happen but it does. Also if I call model.decreaseHealth(10,1) on its own without model.decreaseHealth(10,0) the code works fine also and the healthbars update properly.

help me please!
