Something like this should be good
would return the index if the word is found
will return -1 if no word found matching the given string with wild card
do not forget to populate the index

class Lookup
    static List<String> words;

    static int isPresent(String lookup)
        int index = lookup.indexOf('*');
        String l1 = lookup.substring(0, index);
        String l2 = lookup.substring(index + 1);

        for (int i = 0; i < words.size(); i++)
            if (words.get(i).substring(0, index).compareTo(l1) == 0
                && words.get(i).substring(index + 1).compareTo(l2) == 0)
                return i;

        return -1;
