I have a simple list of results, and I need to return only one value depending on content, for example:

public static void main(String[] args) {
    List<String> results = new ArrayList<>();
    results.add("ERROR");
    results.add("ERROR");
    results.add("OK");
    System.out.println(search(results));
}

public static String search(List src) {
    if (searchValueInStream(src, "ERROR")) {
        return "ERROR";
    } else if (searchValueInStream(src, "OK")) {
        return "OK";
    }
    return "NA";
}

public static boolean searchValueInStream(List src, String str) {
    return src.stream().anyMatch(v -> v.equals(str));
}

this code works fine, but looks not good, and I want to use it in same stream like

String result = results.stream()
 .someFilter(v->v.equals(ERROR)? return "ERROR")
 .someFilter(v->v.equals(OK)? return "OK")
 .orElse("NA");

without “if then else” statement. Is this possible ?
