To convert a JSONArray to a List<Map<String, String>> in Java, you can utilize the Jackson library's ObjectMapper for efficient parsing. Here's how you can achieve this:

1. Add Jackson Dependency:

Ensure that the Jackson library is included in your project. If you're using Maven, add the following dependency to your pom.xml:

<dependency><groupId>com.fasterxml.jackson.core</groupId><artifactId>jackson-databind</artifactId><version>2.17.0</version>
</dependency>

2. Convert JSONArray to List<Map<String, String>>:

Assuming you have a JSON array string, you can parse it as follows:

import com.fasterxml.jackson.core.type.TypeReference;
import com.fasterxml.jackson.databind.ObjectMapper;public class JsonArrayToListMap {public static void main(String[] args) {String jsonArray = "[{\"key1\":\"value1\", \"key2\":\"value2\"}, {\"keyA\":\"valueA\", \"keyB\":\"valueB\"}]";ObjectMapper mapper = new ObjectMapper();try {// Convert JSON array string to List<Map<String, String>>List<Map<String, String>> list = mapper.readValue(jsonArray, new TypeReference<List<Map<String, String>>>(){});// Iterate through the list and print each mapfor (Map<String, String> map : list) {System.out.println(map);}} catch (Exception e) {e.printStackTrace();}}
}

Explanation:

• ObjectMapper: Jackson's ObjectMapper is a powerful tool for converting between Java objects and JSON.

• TypeReference: The TypeReference is used to define the target type for the conversion. In this case, it's a List<Map<String, String>>.

• readValue: This method reads the JSON input and converts it into the specified type.

  {key1=value1, key2=value2}
  {keyA=valueA, keyB=valueB}
  

  This approach ensures that your JSON array is accurately converted into a list of maps, with each JSON object represented as a Map<String, String> in the list.
