Java mapping issue

Question

Basically the program is supposed to search through a text file and find the amount of occurrences of different words and store them in an array and then display the word and the amount of times to the user. I tried using the map class but that was not successful due to the fact that it won't display the results. So I was wondering if anyone knows any other ways I could fix this file:

public class WordStats {


public static void main(String[] args) {
    File textFile = new File("words.txt");
    FileReader in;
    BufferedReader readFile;
    char charInFile;
    String newWord = "";
    String map=new String();
    String existingMap=new String();
    int wordIndex, index = 0;
    ArrayList wordList = new ArrayList();

    /* navigating the file */
    try{
        in = new FileReader(textFile);
        readFile = new BufferedReader(in);
    do{
        charInFile = (char)readFile.read();
        if(charInFile >= 'a' && charInFile <= 'z'){
            while(charInFile >= 'a' && charInFile <= 'z'){
                newWord += charInFile;
                charInFile = (char)readFile.read();
            }//end of while
            wordIndex = wordList.indexOf(map);
            if(wordIndex > -1){
            existingMap = (String) wordList.get(wordIndex);

             //existingMap.addOccurrence();

             wordList.set(wordIndex, existingMap);
            } else {
                index = 0;

            } 
            if(wordList.size() > 0){
                do{
                    existingMap = (String) wordList.get(index);
                    index += 1;
                }while(existingMap.compareTo(map) <= 0 && index < 
wordList.size());
                wordList.add(index-1, map);
            }else{
                wordList.add(map);
            }

        }//end of if
        newWord = "";
    }while(charInFile != (char)-1);

    System.out.println("Word\t\tOccurrences");

        for(Object Word : wordList){
            System.out.println(Word);
        }
        readFile.close();
        in.close();
    }catch(FileNotFoundException e){
        System.out.println("file could not be found.");
        System.err.println("FileNotFoundException: " + e.getMessage());
    }catch(IOException e){
        System.out.println("problem reading the file.");
        System.err.println("IOException: " + e.getMessage());
    }
  }
}
