Handling JSON in Java can be done using Jackson, Gson, or org.json. Jackson (best for large projects): Use ObjectMapper to parse JSON into Java objects. ObjectMapper objectMapper = new ObjectMapper(); User user = objectMapper.readValue(json, User.class); Gson (lightweight): Use Gson to convert JSON to objects. Gson gson = new Gson(); User user = gson.fromJson(json, User.class); org.json (manual handling): Parse JSON using JSONObject. JSONObject obj = new JSONObject(json); String name = obj.getString("name"); Jackson is the most powerful choice. read less

To handle a JSON response in Java, you typically use a library like Jackson or Gson. These libraries help parse JSON data into Java objects. First, you need to retrieve the JSON response (often from an API or a file). Then, using the library, you map the JSON structure to Java objects, such as classes or maps, based on the JSON keys and data types. This allows you to work with the data in a structured and programmatically manageable way, rather than manually extracting values from the raw JSON string. read less
