java deserialize json object

To deserialize a JSON object in Java, you can use the org.json library. Here's an example of how to do this:

import org.json.JSONObject;
import org.json.JSONException;

// Sample JSON object
String jsonObjectString = "{\"name\":\"John\",\"age\":30,\"city\":\"New York\"}";

try {
    JSONObject jsonObject = new JSONObject(jsonObjectString);
    String name = jsonObject.getString("name");
    int age = jsonObject.getInt("age");
    String city = jsonObject.getString("city");
    System.out.println("Name: " + name + ", Age: " + age + ", City: " + city);
} catch (JSONException e) {
    e.printStackTrace();
}

This will output the following:

Name: John, Age: 30, City: New York

You can also use other JSON parsing libraries, such as Gson or Hymanson, to parse JSON objects in Java.
