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(); 
// ...
