I have a function to calculate score

one Simple example

I hava four Option [a,b,c,d] Usually a is 1 score，b is 2 score，c 3 ,d 4 but a few question `Reverse score a=4，b=3 c=2，d=1 I have 20 Answer [a,b,c,a,c,c,a...] I want to calculate finally score。

Is there a simple method calculation this func in java or drools? Now，I used a Stupid method for loop and a lot if

package rules;

import com.neo.drools.entity.UserQuestionAnswer;
import java.util.List;
import java.util.ArrayList;


rule "Scale02"
    //UserQuestionAnswer.questionAnswers
    when
        $q: UserQuestionAnswer(userScore==0)
    then
       $q.setUserScore(getScore($q.getQuestionAnswers()));
       System.out.println("Score: "   $q.getUserScore());
end

function int getScore(List answers) {
//answers index (8、20、24、37、43、48、52) =="A"  1分 13、33、56 == "B"  1分
        int score = 0;
        if (answers.get(7).equals("A")) {

CodePudding user response：

Assuming your answers are ordered and the reversed ones are known you can try something like this:

Map<String, Integer> scores = Map.of("a", 1, "b", 2, "c", 3, "d", 4);
Map<String, Integer> reversedScores = Map.of("a", 4, "b", 3, "c", 2, "d", 1);

List<String> options = List.of("a", "b", "c", "a", "c", "c", "a", "d", "d", "d", "b", "a", "c", "a", "a", "d", "b", "c", "b", "d");
List<Integer> reversedQuestions = List.of(3, 5, 6, 10, 14, 15);

Integer finalScore = IntStream.range(0, options.size())
        .map(i -> reversedQuestions.contains(i)
                ? reversedScores.get(options.get(i))
                : scores.get(options.get(i)))
        .sum();
