Java validating input values

Question

 private String createSearchFieldContent(OverrideableStringValue title,
                                         OverrideableContactValue owner) {

    StringBuilder builder = new StringBuilder(getValue(title));

    if (StringUtils.isNotBlank(getValue(owner).getFamilyName())) {
        builder.append(" ").append(getValue(owner).getFamilyName());
    }

    String searchTerm = StringUtils.replaceAll(builder.toString(), "\n", " ");

    return unaccent(searchTerm);
}

There are four values, which I get from an API and they are not possible as familyName. Is there a way to don't add them to the searchTerm? I'm thinking about something like StringUtils.contain() and then there the invalid values...

Thanks for help!

create exception? what exception? in which cases? is it throwing an exception? are you trying to throw one yourself?µ — Stultuske, Nov 21 '19 at 07:04
@Stultuske exception would be the best way but I'm not pretty sure how I can do that correctly — macintosh, Nov 21 '19 at 07:15
do what correctly, you're still not being clear about what it is you're trying to do — Stultuske, Nov 21 '19 at 07:25
@Stultuske I got some values which are not allowed and I know these values. I like to add an exception for those four values - if I get these values, it shouldn't add them to the string — macintosh, Nov 21 '19 at 08:23

If you know what 4 values from API should not be appended then declare as constants. Now there are 2 ways from here : 1) Either compare all those 4 constants with family name or 2) Add them in hashset then use contains check with family name
