When you subscribe to the Value attribute you receive a DataValue, which has as StatusCode component.

hi，kevinherron，thank you for your reply , but why when the opc ua server quality stamp is bad, but the StatusCode in the DataValue received by the opc ua client is good.

As indicated in code:

    private static String quality(StatusCode statusCode) {
        if (statusCode.isGood()) {
            return "good";
        } else if (statusCode.isBad()) {
            return "bad";
        } else if (statusCode.isUncertain()) {
            return "uncertain";
        } else {
            return "unknown";
        }
    }

quality is just a string name for status code name.
