    In java, parameters are passed by value and not by reference. Therefore, you cannot change the reference of a parameter.

    In your case, you need to do:

    public static String getRandomWord() {
        switch(new Random().nextInt(5)) {
            case 0:
                return "Peace";
            case 1:
                return "Nuts";
            // ...
            default:
                throw new IllegalStateException("Something went wrong!");
        }
    }
    

    And in main:

    // ...
    String word = getRandomWord();
    int len = word.length(); 
    // ...

    You can't modify the caller's reference.

    RandomWord(word);
    

    needs to be something like

    word = RandomWord(word);
    

    Also, by convention, Java methods start with a lower case letter. And, you could return the word without passing one in as an argument and I suggest you save your Random reference and use an array like

    private static Random rand = new Random();
    public static String randomWord() {
        String[] words = { "Peace", "Nuts", "Cool", "Fizz", "Awesome" };
        return words[rand.nextInt(words.length)];
    }
    

    And then call it like

    word = randomWord();
