如何用java实现JSON数组乘法？JSON数组

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonArrayMultiplication {
    public static void main(String[] args) {
        String jsonArrayStr = "[1, 2, 3, 4, 5]";
        int multiplier = 2;

        try {
            ObjectMapper objectMapper = new ObjectMapper();
            JsonNode jsonArray = objectMapper.readTree(jsonArrayStr);

            for (int i = 0; i < jsonArray.size(); i++) {
                int element = jsonArray.get(i).asInt();
                int multipliedElement = element * multiplier;
                jsonArray.set(i, objectMapper.convertValue(multipliedElement, JsonNode.class));
            }

            String resultJsonArrayStr = objectMapper.writeValueAsString(jsonArray);
            System.out.println(resultJsonArrayStr);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
