I don't know any Apache String joiner that can support adding and in the joined String.

Here's an untested code that will do what you asked:

public static String join(String separator, List mList, boolean includeAndInText) {
    StringBuilder sb = new StringBuilder();
    int count = 0;

    for (String m: mList) {
        if (includeAndInText && (count + 1 != mList.size())) {
            sb.append (" and ");
        }

        sb.append(m);
        count++;
        if (count < mList.size()) {
            sp.append(separator);
        }       
    }

    return sb.toString();
}
