Hello,

I am writing a program that, in its setup, wants to read words from a text file and save them into an object of class word, along with the coordinates of the word-objects center, and a randomly generated greyscale value fill. I want processing to arrange the word squares in a grid pattern, which doesn't seem like it would be too tricky (I'm new to both processing and programming) but I'm having some issues:

This is my code so far:

ArrayList words;

void setup() {
 
  size(600, 600);
  words= new ArrayList();
 
  BufferedReader reader = createReader("Story.txt");
 
  String currentLine;
  String wholeStory;
 
  //add all of the txt to one string
try {
  while ((currentLine = reader.readLine()) != null) {
   
    wholeStory+=currentLine;
    }
}
catch (Exception e) {
  e.printStackTrace();
}

  //take out all punctuation using regex, make new word object containing a word,
  //and add it to the array
 //Pattern parserPat = Pattern.compile("([a-zA-Z]*?)");

 //Matcher wordFinder = parserPat.matcher(wholeStory);

  /*while (wordFinder.find()) {

    Word word = new Word();
    word.setWord("hi");
    words.add(word);
    }*/

  Word word = new Word();
  word.setWord("hi");
  words.add(word);
 
  System.out.println(words);
  System.out.println("here");
  //assign an x and y coordinate to each word object
   
    int closestSquare=(int)(Math.ceil(Math.sqrt(words.size())));
    //length of one side of board
    int squareSide=width/closestSquare;
   
    int count=0;
  
    for (int i=0; i<closestSquare; i++){
          for (int j=0; j<closestSquare; j++){
           
              words.get(count).setCenterX((squareSide/2)+squareSide*j);
              words.get(count).setCenterY((squareSide/2)+squareSide*i);
              words.get(count).setRGB(int(random(255)));
              count++;
            }
          }
   

   //draw the squares
   rectMode(CENTER);
   for(int k=0; k<words.size(); k++){
     fill=word.getRGB();
     rect(word.getCenterX(), word.getCenterY(), squareSide, squareSide);
   }
 }
 
 void Draw(){
    rectMode(CENTER);
   
 }
 
public class Word {
   /*this class is the word object which contains variables for the value of the
word, the coordinates of its center, and its fill color.*/

String value;
int xCenter;
int yCenter;
int greyRGB;

public void setWord(String input){
 
  input=value;
 
}

public String getWord(){
 
  return word;
}

public void setCenterX (int x){
 
  xCenter= x;
}

public int getCenterX (){
 
  return centerX;
}

public void setCenterY (int y){
 
  yCenter= y;
}

public int getCenterY (){
 
  return centerX;
}
public void setColor (int rgb) {
 
  greyRGB= rgb;
 
}

public int getColor(){
 
  return greyRGB;
}

public String toString(){
  return value;
 }
 }

and the issue is that not only is it not seeing internal methods like setCenterX(), it's not even printing my println, even when outside of the while-loop. Also, was fretting about my regex, and not compliling "ArrayList<Word>" words.

I'm thinking about ditching my internal class entirely and using hashmaps, but it seems like I'm missing some trivial beans.
