send the token value to the function as an array.

String fillInString(String str, String ... token){
    return String.format(str, token);
}

var args like this can accept seperate arguments or an array.

String fillInString(String str, ArrayList<String> token){
    return String.format(str, token.toArray(new String[token.size()]));   
}
