How to access an array when it is within an arraylist?

The overall goal of what I'm trying to do is to compare a string to index 0 of an array (that is held within an arraylist), and if the strings are the same (ignoring case), call a method that matches the case of the string to the translated word (held at index 1 of the array inside an arraylist). When I run this code and I print out the contents of my translated arraylist, I get all "no match" characters. I'm assuming this is because I'm not accessing the index I want in the correct manner. Please help!

public static String translate(String word, ArrayList<String[]> wordList) { 
    if (word == "." || word == "!" || word == ";" || word == ":") {
        return word;
    }
    for (int i = 0; i < wordList.size(); i++) {
            String origWord = wordList.get(i)[0];
            String transWord = wordList.get(i)[1];

            if (word.equalsIgnoreCase(origWord)) { //FIXME may need to change if you need to switch from translated to original
                String translated = matchCase(word, transWord);
                return translated;
            }
    }
    String noMatch = Character.toString(Config.LINE_CHAR);     


    return noMatch;
}

Sample Data and expected result

word = "hello"

wordList.get(i)[0] = "Hello"

wordList.get(i)[1] = "Hola"

(word and wordList.get(i)[0] match, so the next step is executed)

match case method is called and returns the translated word with the same case as the original word ->

translated = "hola"

returns the translated word.

(the for loop iterates through the entire wordList until it finds a match, then it calls the translate method)

Match Case's Code

 public static String matchCase(String template, String original) {
    String matched = "";
    if (template.length() > original.length()) {

        for (int i = 1; i <= original.length(); i++) {
            if (template.charAt(i-1) >= 'a' &&  template.charAt(i-1) <= 'z') {

                if (i == original.length()) {

                matched +=  original.substring(original.length() - 1).toLowerCase();

                }
                else {

                    matched += original.substring((i-1), i).toLowerCase();
                }

            }
            else if (template.charAt(i-1) >= 'A' && template.charAt(i-1) <= 'Z') {
                if (i == original.length()) {

                    matched += original.substring(original.length() - 1).toUpperCase();

                }
                else {

                    matched +=  original.substring((i-1), i).toUpperCase();

                }
            }
        }
        return matched;
     }
     else if (template.length() < original.length()) {
         int o;
            original.toLowerCase();
            for (int i = 1; i <= template.length(); i++) {
                if (template.charAt(i-1) >= 'a' &&  template.charAt(i-1) <= 'z') {
                    if (i == template.length()) {
                        matched += original.substring(original.length() - 1).toLowerCase();
                    }
                    else {
                        matched += original.substring((i-1), i).toLowerCase();
                    }
                }
                else if (template.charAt(i-1) >= 'A' && template.charAt(i-1) <= 'Z') {
                    if (i == template.length()) {
                        matched += original.substring(original.length() - 1).toUpperCase();
                    }
                    else {
                        matched += original.substring((i-1), i).toUpperCase();
                    }
                }
                String newMatched = matched + original.substring(i, original.length() - 1);
                matched = newMatched;
                newMatched = "";
            }

            return matched;
     }

   return original; 
}
