Comparing a text file with two different text files

Hello all,
I'm new to Processing and programming as a whole, so please bear with me.

I am trying to vizualize a book (Beyond good and evil) by comparing it with two text files -- one a database of positive words, the other a database of negative words. This is what i have so far:
String[] beyond;

String[] posText;

String[] negText;

String delimiters = " ,.?!;:\n";

int x = 0;

int y = 0;

Map<String, Integer> words = new HashMap<String, Integer>();

void setup(){

background (255);

size (200, 200);



String[] myText = loadStrings ("bge.txt");

// Join the big array together as one long string

String everything = join(myText," ");

// Split the array into words using any delimiter

beyond = splitTokens(everything,delimiters);



String[] posText = loadStrings ("positive-words.txt");

String posLexicon = join(posText, " ");

posText = splitTokens(posLexicon,delimiters);



String[] negText = loadStrings ("negative-words.txt");

String negLexicon = join(negText, " ");

negText = split(negLexicon,delimiters);



// 0 is negative, 1 is positive

words.put("posText", 1);

words.put("negText", 0);



// go through each word from myText

for(int i=0; i < myText.length; i++) {



// check if its in the text

if(words.get(myText[i]) == null){

noFill();

}else{

if(words.get(myText[i]) == 0){

fill(175);

}else if(words.get(myText[i]) == 1){

fill(0);

}

}



for(x = 0; x < width; x+=10) {

for(y = 0; y < height; y +=10) {

rect(x,y,10,10);

}

}

}

}
I'm pretty sure something is wrong with the HashMap -- I've never used nor fully unterstood the bastard --, specifically lines 30 and 31. Instead of getting a nice pattern of red pixels (negative words in the book) and white pixels (positive words), I just get empty pixels.

If ye nice people can help me, I'd be really grateful.

Peace!
