How can I convert an error handling method into a Lambda function

Question

Is there a way this method could be modified into a lambda function?

public static <T> void checkResponse(Response<T> response, String errorMessage, Map<String,String> values) throws IOException {
    if (!response.isSuccessful()) {
        String message = StringSubstitutor.replace(errorMessage, values);
        logger.error(message);
        throw new RuntimeException(message, null);
    }
}

Answer 1

First, define an interface with the appropriate parameters, then you can use a lambda to implement it.

@FunctionalInterface
interface ResponseHandler<T> {
   void handleResponse(Response<T> response, String errorMessage, Map<String,String> values);
}
// ...
ResponseHandler handler = (response, errorMessage, values) -> {
    if (!response.isSuccessful()) {
        String message = StringSubstitutor.replace(errorMessage, values);
        logger.error(message);
        throw new RuntimeException(message, null);
    }
};
// Call it:
handler.handleResponse(...);
